    ABSTRACT: Makrofol BL 2-4 is an extrusion film based on Makrolon polycarbonate. It is different from Makrofol DE as it comprises excellent die-cutting performance combined with high light transmission and moderate light scattering properties. It is a polymeric solid-state nuclear track detector, which has many applications in various radiation detection fields. Samples from Makrofol BL sheets were irradiated using different electron beam doses ranging from 20 to 300 kGy. It is worth mentioning that this report is almost the first one dealing with this topic of material changes using Makrofol BL 2-4. The resultant effect of electron beam irradiation on the properties of Makrofol has been investigated using X-ray diffraction, intrinsic viscosity, Fourier transform infrared spectroscopy, thermogravimetric analysis, refractive index, and color difference studies. The results indicate that the electron beam irradiation in the dose range 50–200 kGy led to the dominance of cross-linking, enhancing the properties of Makrofol.

    ABSTRACT: Because of the estrogenic effect of bisphenol A (BPA), the application of BPA derivatives such as Bis-GMA in dentistry has been doubted. In this research, Bis-GMA-free dental resin systems were prepared by mixing 1,6-bis(2′-methacryloyoxy-ethoxycarbonyl-amino)-2,4,4-trimethylhexane (UDMA), silicon containing dimethacrylate monomer (SiMA), and triethyleneglycol dimethacrylate (TEGDMA) together with different mass fraction. Double bond conversion, polymerization shrinkage, flexural strength, flexural, water sorption, and water solubility of prepared resins were investigated. Results showed that when UDMA/SiMA/TEGDMA was present in the ratio of 9:1:10 (wt/wt/wt), the obtained resin had the best comprehensive physicochemical properties and potential to be used as Bis-GMA-free dental resin.

    ABSTRACT: The development of simple methods for the removal of heavy metal cations from water samples is a relevant field of research. For this purpose, poly(aniline-co-m-phenylenediamine) (PAMpDA) was synthesized via radical oxidation polymerization of aniline with m-phenylenediamine. Then, superparamagnetic poly(aniline-co-m-phenylenediamine)@Fe3O4 (PAMpDA@Fe3O4) nanocomposite was fabricated from PAMpDA, Fe(II), and Fe(III) salts via the in situ coprecipitation technique. The products were characterized in terms of chemical structure, morphology, thermal and magnetic properties by Fourier transform infrared, X-ray diffraction, scanning electron microscopy, thermal gravimetric analysis, and vibrating sample magnetometer, respectively. The capability of PAMpDA and its nanocomposite for the removal of Pb(II), Cd(II), and Co(II) ions was investigated at various contact times, absorbent dosages, pH, and initial concentrations. The experimental data for Co(II) cation with the highest sorption were analyzed by two isotherms and kinetic equations. In addition, the electrical conductivity of PAMpDA and PAMpDA@Fe3O4 nanocomposite was examined after sorption of the heavy metal ions.

    ABSTRACT: In this research, we investigate the influence of polyvinylpyrrolidone (PVP) solution systems on the morphology of the PVP nanofibers fabricated by electrospinning of PVP solutions prepared in different organic solvents, including ethanol (EtOH), propanol (PrOH), chloroform, N-methyl-2-pyrrolidone (NMP), and N,N-dimethylformamide (DMF) and then compared with the experimental results. First, by considering the electrospun solutions behavior, the thermodynamic studies were evaluated then Hansen solubility theory was applied to select the desirable solvent systems. The dissolving power of the solvents for PVP was obtained in the following order: DMF > NMP >> chloroform > PrOH > EtOH. It seems that every solvent, which is able to dissolve PVP polymer, shows different spinning characteristics under identical conditions of processing parameters. By using PrOH, chloroform, and NMP solvents, electrospun nanofibers’ average diameter was decreased intensively but at the same time beads formation was observed. We investigated that EtOH was a desirable solvent for PVP to fabricate fibers with z micrometer diameter distribution, but because of its low dissolving power it is suitable for microfiber synthesis with the electrospinning process. Based on the Hansen theory and experimental results, the PVP/DMF solutions showed desirable characteristics for the electrospinning system. Furthermore, the PVP nanofiber's uniformity of the PVP/DMF solution was higher than other solvent systems, which mean that fiber diameter distribution is scanty than others. Finally, it has been demonstrated that with an appropriate solvent the nanofiber diameter distribution and formation of beads can be controlled by Hansen theory.

    ABSTRACT: In this work, blend nanoparticles of poly(3-hexylthiophene) (P3HT) and phenyl-C61-butyric acid methyl ester (PCBM) were prepared with different composition ratios, namely 50:50, 60:40, and 70:30. Larger particle size is found for the blend nanoparticles with higher P3HT content, as measured by dynamic light scattering and transmission electron microscopy. The blending of nanoparticles did not affect the optical properties of the two materials as indicated by the UV–vis absorption spectra. The photoluminescence spectra of the blend nanoparticles reveal an efficient charge separation reflected by the quenching of the P3HT emission band by the PCBM. The quenching efficiency increases as the content of the PCBM increases. Good layer morphologies were obtained from casting the blend nanoparticles. The layer morphology was further improved by thermal annealing as indicated from the atomic force microscopy results. The water-based dispersions offer a promising straightforward strategy toward the large-scale fabrication of organic solar cells.

    ABSTRACT: Attapulgite/polypyrrole (ATP/PPy) nanocomposite, which is well defined with nanoscale rod-like morphology, was prepared in the presence of phosphorylated polyvinyl alcohol (PPVA–ATP/PPy) by chemical oxidative polymerization. PPVA functioned as both the dopant and the dispersant in this work. The composites possess good dispersion stability, high electrical conductivity at room temperature, and weak temperature dependence of the conductivity. Moreover, it was found that their dispersion stabilities in water increased with the increasing feeding ratio of PPVA. In addition, the thermal stability of conductivity PPVA–ATP/PPy composites was also enhanced by PPVA.

    ABSTRACT: The flame-retardant and flexural mechanical properties for the polypropylene (PP) composites filled with intumescent flame retardant (IFR) were measured. It was found that the limited oxygen index increased roughly linearly, whereas the horizontal combustibility rate decreased with increasing theIFR weight fraction; when the IFR weight fraction was more than 10%, the smoke density rank decreased with increasing the IFR weight fraction; the flexural modulus and the flexural strength increased when IFR weight fraction was lower than 20% and then decreased with increasing the IFR weight fraction; the values of the flexural modulus and the flexural strength reached to the maximum at the IFR weight fraction of 10%. Moreover, the flexural modulus and the flexural strength of the composites were higher than that of the unfilled PP resin.

    ABSTRACT: A candid approach to thermal dehydroxylation was used for the modification of clay, to achieve improved thermal stability of a polymer nanocomposite. The modification of clay using alkyl ammonium salt has been found disadvantageous due to various aspects; hence the approach to dehydroxylation was an innovative step to overcome the difficulties in achieving a thermally stable polymer clay nanocomposite. Therefore, a detailed study of thermal stability of polymer clay nanocomposites has been carried out using isoconversional TGA methods of Flynn–Wall–Ozawa and Kissinger. Also, the reaction model involved in the decomposition process of polypropylene (PP) and its nanocomposites have been investigated. From the thermal kinetic analysis, it was clear that the thermal dehydroxylation method can be used as an effective approach for clay modification and the use of organic alkyl ammonium salt can be avoided. Furthermore, to predict the flame-retardant effectiveness of the thermally dehydroxylated clay, the cone calorimeter analysis was carried out. A comparison of the flame-retardant effectiveness of the organophillic clay and thermally dehydroxylated clay was presented.

    ABSTRACT: Two new intrinsically conducting polythiophenes, poly-1,4-bis(3-hexylthiophene)-dibutyne (P1) and poly-2′-thiophene-5-hexyl-2,3′-bithiophene (P2), are synthesized to improve the processability of polythiophene. P2 exhibits alternating thiophene and alkylthiophene rings, whereas P1 is characterized by triple bonds between alkylthiophene rings. Both polymers are characterized in terms of chemical, electrical, thermal, and mechanical properties using different techniques. The electrical conductivity of both polymers was determined, their values being significantly lower than that of polythiophene. However, the processability of P1 and P2 was higher in comparison with that of polythiophene because the compression process was possible. The conductivity range makes them suitable for electronic applications.

    ABSTRACT: In this paper, the mechanical properties of sunflower oil-span 40-natural gum bigels were evaluated. The bigels were prepared by mixing the oleogels of sunflower oil-span 40 and the hydrogels of natural gums. The types of molecular interactions occurring were studied by FTIR spectroscopy. Rheological and textural behavior of the bigels was determined by dynamic rheological studies and a static mechanical tester. The Peleg and Normand equation was used to determine the viscoelastic behavior of the bigels. The efficiency of these food-grade bigels as carriers for the delivery of metronidazole (model drug) was studied. In vitro drug release was carried out under physiological conditions. The antimicrobial efficiency of the bigels was checked against Escherichia coli. FTIR studies showed hydrogen bonding within the bigels as the major molecular interaction. The rheological and mechanical studies showed that the bigels exhibited pseudoplastic flow behavior. The bigels were viscoelastic in nature. Diffusion mediated drug release was observed. All the bigels showed an equal antimicrobial efficacy in comparison to the available marketed formulation.

    ABSTRACT: The cross-linked cassava xanthate (CCX) was synthesized and used to remove Cr6+ ions from aqueous solution. The influence of multiple factors on the sorption process, including pH, temperature, contact time, sulfur content, and sorbent/sorbate ratio, was quantitatively investigated. The sorption capacity of the CCX was confirmed under different conditions. The adsorption equilibrium was fitted to Langmuir and Freundlich isotherms. The Cr-containing cross-linked cassava xanthate (CCX-Cr) could be cyclically regenerated by HNO3 solution. The pyrolysis of the CCX and CCX-Cr was measured using Fourier transform infrared spectroscopy and thermo-gravimetric/differential thermal analysis coupling method. The CCX had higher percentage of the residues than the CCX-Cr due to the ion exchange mechanism in the adsorption process.

    ABSTRACT: In this study, surface modifications of poly(vinyl chloride) (PVC) films were performed with the plasma polymerization process. For this purpose, allylamine was used as a hydrophilic polymer for surface modification of PVC films. The wettability of PVC films was investigated using contact angle measurement. The water contact angle values increased from 116.4° to 12° by 104.4° for the coated PVC film. Surface free energies of PVC films were calculated using acid–base approaches and increased with increasing plasma treatment time. According to the Fourier transform infrared spectroscopy results, N–H peaks appeared in the expected wavelength. The thermal degradation behaviors of PVC films were investigated by thermogravimetric analysis. The degradation temperature of PVC films was altered by the plasma treatment from 275°C to 380°C. Surface topography of PVC films was examined by atomic force microscopy (AFM). Distinct changes were observed in the topography of plasma-treated PVC surface using AFM results. The results showed that allylamine plasma treatment can be used to enhance hydrophilicity of PVC surfaces.

    ABSTRACT: A series of chemically cross-linked hybrid composite hydrogel systems containing polysaccharide/clay polyelectrolyte based on the acrylamide/sodium methacrylate (AAm/SMA) and ɩ-carrageenan and clay such as montmorillonite were synthesized with free radical solution polymerization by using ammonium persulfate/N,N,N',N'-tetramethylethylenediamine as a redox-initiating pair in the presence of poly(ethylene glycol) diacrylate as a cross-linker. Fourier transform infrared spectroscopy (FT-IR) analysis and scanning electron microscopy (SEM) technique were applied for characterization. The hydrogels, the semi-interpenetrating polymer networks (semi–IPNs), and the hybrid composite hydrogel systems that were synthesized in this study have shown high water absorbency. Some swelling and diffusion properties were calculated, and they were discussed for the hybrid hydrogel systems prepared under various formulations. They were used in experiments on sorption of water-soluble cationic dye such as Safranin T (ST). The sorption of ST into the polymeric systems was studied by a batch sorption technique at 25°C. For equilibrium sorption studies, dye removal capacity, adsorption percentage, and partition coefficient of the hydrogels, the semi-IPNs, and the hybrid composite hydrogel systems are investigated. Consequently, the hydrogels, the semi-IPNs, and the hybrid composite hydrogel systems developed in this study could serve as a potential device for water and dye sorbents. Some materials such as the hydrogels, the semi-IPNs, and the hybrid composite hydrogel systems developed in this study with the ability to absorb water in high amounts could be used as a water and dye sorbents because of their potential applications in agriculture, environment, separation processes, and water purification.

    ABSTRACT: Natural rubber powder (NRP) was prepared by spray drying and optimized via statistical experimental design. The yield of NRP obtained significantly depended on the percentage of dry rubber content (DRC) and the amount of sodium dodecyl sulfate (SDS). The optimum condition for spray drying was found to be with an inlet air temperature of 130°C, a feed rate of 4 mL min−1, nozzle flow rate of 600 L h−1, 15% DRC, and 12 parts per hundred of rubber (phr) of SDS. Under these conditions, a NRP yield of 44.9%, and a total solid recovery of 98.7% with a moisture content of 0.4% was obtained. The resultant NRP particles were almost spherical with a diameter of less than 10 μm. The mechanical properties of NRP, in terms of the modulus, tensile strength, and hardness were greater than that for conventional block rubber (STR). Moreover, the addition of silica filler (25 phr) yielded better mechanical properties when prepared by spray drying (Si/NRP) than by the conventional silica-filled block rubber (Si/STR). Scanning electron microscopy revealed that the silica was more remarkably evenly dispersed in the rubbery matrix of the Si/NRP composite compared to the agglomerated clumps found in the Si/STR composite prepared by the conventional mechanical mixing method.

    ABSTRACT: This paper deals with the fabrication and characterization of raw and surface-modified Grewia optiva fibers reinforced unsaturated polyester (UPE) matrix based composites. Raw and surface-modified fibers are used in different proportions (10, 20, 30, and 40%) for the fabrication of composites. The fiber proportion is optimized by studying various mechanical properties such as tensile, compressive, and flexural strength of UPE matrix-based composites. After the optimization of fiber loadings, the optimized samples were evaluated for their physicochemical, thermal, fire retardancy, and biodegradability properties. Physicochemical and thermal stability of the composites is improved after fibers’ surface modification. The effect of different fire retardants (magnesium hydroxide and zinc borate) on the fire-retardant behavior of polymer composites is also evaluated. Biodegradability of polymer composites is checked by using a soil burial method.

    ABSTRACT: The main aim of this study was to investigate the usability of polyurethane (PU) and polyacrylonitrile (PAN) nanofibers for improving the sound absorption of conventional polyester nonwovens in wide band of frequencies along with weight and thickness reduction. The effect of nanofiber and nonwoven layers number, nanofiber layers surface density, and the type of nanofiber polymer on the sound absorption was studied. To find the optimum conditions for achieving high sound absorption, response surface methodology was used. The results showed that the sound absorption of composite samples is improved when the nanofiber layer number or its surface density increased. The results also showed that the sound absorption of composites is enhanced by using PAN instead of PU. At a constant surface density, the higher resonant peak, without shifting, was achieved with increasing the nanofiber layers number. Optimization process showed that samples containing PAN nanofiber layers with surface density of 4.72 g/m2 and six nonwoven layers have highest average sound absorption coefficient.

    ABSTRACT: In this research, polyethersulfone (PES)/polyacrylonitrile (PAN) blend ultrafiltration hollow fiber membranes were prepared via phase inversion induced by a dry-jet wet spinning process. The membranes were characterized by water contact measurements, scanning electron microscopy analysis and permeability measurements, and fouling-resistance measurements. The results show that water contacts of the membranes are enhanced by increasing the PAN content in the spinning dope. The results of an experimental study on separation of oil from oily wastewaters are presented. The results demonstrated that the prepared PES membranes are effective in removing chemical oxygen demand (80.6%), total organic carbon (89.3%), turbidity (99.3%), total suspended solid (100%), and oil and grease content (99.7%), and final permeation flux of about 73.5 L/m2h. Also, it was found that 75/25 wt% of PES/PAN have higher mechanical strength and good separation performance. Hermia's models were used for prediction of the decline in permeation flux. Experimental data and models predictions were compared. The results showed that there is reasonable agreement between experimental data and the cake layer model followed by the intermediate blocking model.

    ABSTRACT: In this work, ortho cresol novalac resin was synthesized in the laboratory and this synthesized resin was further reacted with epichlorohydrin to obtain ortho cresol novalac epoxy resin (OCNE). The obtained resin can be characterized by FTIR analysis. The OCNE-based composites were produced by filling the nano-SiC particulates. To explore the mechanical and tribological characteristics of these composites under dry sliding conditions, the effects of nanoparticles on the mechanical, friction, and wear properties of the OCNE composites filled with 1–4 wt% of SiC particulates (40 nm) were evaluated using a pin-on-disk apparatus. The improvement in the mechanical and wear properties was attributed to high strength, high hardness, and good dispersion of nano-SiC particulates, which can enhance the interfacial properties of nanofiller and the epoxy matrix. The lowest coefficient of friction and the specific wear rate of composites were 0.27 and 2.18 × 10−08 mm3/Nm, respectively. A positive synergetic effect was also found, and the proposed quaternary composites might be applicable in practice. The wear mechanisms of these composite specimens were examined with the help of a scanning electron microscope equipped with an energy dispersive x-ray analyzer and an x-ray diffractometer .
