    ABSTRACT: This paper reports a study on erosion response of epoxy composites filled with micro-sized Linz–Donawitz (LD) slag particles. LD slag is a major solid waste generated in huge quantities during steel making. It comes from slag formers such as burned lime/dolomite and from oxidizing of silica, iron etc. while refining the iron into steel in the LD furnace. Although a number of ways for its utilization have been suggested in the past, its potential as a filler material in polymeric matrices has not yet been explored. In this work, composites of five different compositions (0, 7.5, 15, 22.5 and 30 wt% of LD slag reinforced in epoxy resin) are prepared by a simple hand layup technique. The composites are characterized in regard to their density, porosity, micro-hardness and strength properties. Erosion trials (ASTM G 76) are conducted on the composite samples following a well-planned experimental schedule based on Taguchi's design of experiments. The study reveals that the impact velocity and LD slag content in the composites are the most significant among various factors that influence the wear rate. This work shows that LD slag, in spite of being a waste, possesses fairly good filler characteristics as it modifies the properties and improves the erosion resistance of the polymeric resin.

    ABSTRACT: A molecularly imprinted polymer (MIP) for melamine was prepared by suspension polymerization, using melamine as a template, methacrylic acid as a functional monomer, and ethylene glycol dimethacrylate as a cross-linker. The optimal template/monomer and monomer/cross-linker ratios were obtained, being defined as 1/15 and 1/12, respectively. Molecular recognition properties and binding capacity toward melamine were evaluated by adsorption tests. Compared with the nonimprinted polymer, the imprinted polymer showed higher affinity for melamine with a dissociation constant (Kd) and a maximum binding concentration of 568.4 ± 7.4 μmol/L and 96.8 ± 2.3 μmol/g, respectively. Under optimal conditions, the imprinted polymer was used as a dispersive extraction sorbent to extract melamine from different milk samples, before high performance liquid chromatography with diode array detection (HPLC-DAD) analysis. The validated method presented a limit of detection of 0.6 mg/kg. From the analysis of six different milks, melamine was detected in two of the considered samples at a maximum concentration of 9.3 ± 0.3 mg/kg.

    ABSTRACT: This study reported the successful synthesis of a new amphiphilic and cationic flocculant (denoted as CS-g-PDBC) by grafting a cationic monomer, dimethyl acryloyloxyethyl benzyl ammonium chloride (DBC), onto chitosan (CS) initiated by ceric ammonium nitrate. The molecular structure and surface morphology of the newly synthesized graft copolymer CS-g-PDBC were characterized in detail by using Fourier transform infrared spectroscopy, X-ray powder diffraction, field emission scanning electron microscope, thermogravimetric analysis , and elemental analysis. Moreover, its flocculation efficiency for treating simulated emulsified oil wastewaters was evaluated and the results indicated that CS-g-PDBC was more efficient than those of CS and two other commonly used flocculants, i.e., cationic polyacrylamide and polyaluminum chloride. It was found that, as compared with CS, the successful introduction of cationic and hydrophobic groups into the CS backbone resulted in a significantly broadened flocculation window and a greatly enhanced flocculation efficiency for the prepared CS-g-PDBC in the treatment of oily wastewater, suggesting that this newly synthesized CS-g-PDBC would be a promising green agent for oily wastewater treatment.

    ABSTRACT: This paper is aimed to study the suitability of poly(lactic acid) (PLA) for the production of biodegradable containers by rotational molding. To increase polymer toughness, PLA was plasticized with poly(ethylene glycole) (PEG), with an average molecular weight of 400 g/mol. Differential scanning calorimetry performed on neat PLA and PEG-plasticized PLA showed that the former is characterized by a better quenchability than the latter. Neat PLA and PEG-plasticized PLA were used for the production of rotational molding prototypes of simple shape. Owing to its very slow crystallization kinetics, a completely amorphous PLA was obtained by rotational molding with air cooling. As a consequence, rotomolded PLA is characterized by a good ductility and toughness. In contrast, the higher crystallization rate induced by the addition of PEG did not allow to obtain an amorphous structure for plasticized PLA, even if faster cooling was attained by water spraying. As a consequence, the PEG-plasticized PLA, characterized by a semicrystalline structure, shows a lower ductility and toughness compared to neat PLA.

    ABSTRACT: Makrofol (KG and N) polycarbonates (PCs) are the most versatile solid-state nuclear track detectors. These polymers were exposed to gamma radiation of doses ranging from 250 to 1000 kGy. The pristine and exposed samples were characterized by X-ray diffraction (XRD), UV–vis spectrophotometry, and Fourier transform infrared spectrophotometry for the structural, optical, and chemical studies, respectively. The XRD studies showed that crystallite size for exposed samples of makrofol-KG PC decreased from 64.7 to 57.9 Å and for makrofol-N PC it increased from 19.1 to 21.1 Å. The band gap energy decreased from 4.40 to 4.07 eV for makrofol-KG and from 4.26 to 3.83 eV for makrofol-N after the gamma exposure. The number of carbon atoms per conjugation length as obtained from UV–vis studies was increased in both cases. The activation energy showed fluctuations for exposed samples of both polymers. The intensity of various absorption bands of the infrared spectra decreased at some doses for both the PCs, indicating the change in the chemical properties of the exposed samples.

    ABSTRACT: A novel diamine monomer was prepared in three steps: first, a nucleophilic substitution reaction between hydroquinone and 1-flouro-4-nitrobenzene afforded a nitro compound. Second, the nitro group of this compound was converted to an amino group via reduction in the presence of hydrazine hydrate. In the last step, the reaction of this compound with 4,4'-diflouro benzophenone led to the synthesis of a novel ether keto diamine. Characterization of all materials was carried out by conventional spectroscopic methods and elemental analysis. A series of new polyureas was prepared via the polymerization reaction of the synthesized diamine with three commercially available diisocyanates including 4,4'-diphenylmethan diisocyanate, toluene-2,4-diisocyanate, and isophoronediisocyanate in N-methyl-2-pyrrolidone. The resulted polyureas were characterized by infrared spectroscopy and elemental analysis. The inherent viscosities of these polyureas ranged from 0.59 to 0.62 dL/g measured at a concentration of 0.5 g/dL. The resulting polyureas were soluble in dipolar aprotic solvents. The thermal properties of the polymers were investigated by differential scanning calorimetry and thermogravimetric analysis. The results indicated that their glass transition temperature values were between 171 and 198°C and at the 10% weight loss of polymers, glass transition temperature was about 325–368°C showing improved thermal stability in comparison with common polyureas. Thermal stability features of the polyurea were also confirmed by means of the pyrolysis-gas chromatography/mass spectrometry method.

    ABSTRACT: Polyurethanes (PUs) are synthesized by reacting two polyols namely bis(2-hydroxyethyl) terephthalate (BHET) and polyethylene glycol (PEG), taken in four different ratios and hexamethylene diisocyanate (HMDI), where the polyol content is slightly higher than the stoichiometrically required amount. BHET is obtained by the glycolysis of polyethylene terephthalate (PET) waste. The synthesized PUs are blended with sodium alginate in the ratio of 7:3 and then crosslinked by calcium chloride to get a pH sensitive protein (bovine serum albumin, BSA) carrier. X-ray diffraction (XRD) patterns of different PU compositions indicate the presence of amorphous phase. Hydroxyl value of OH-terminated polyurethanes is found to be increasing with increasing amount of PEG in the composition. PEG-ylated PU shows higher water uptake and protection against haemolysis with rising amount of PEG in the PU. Fourier transform infrared (FT-IR) spectroscopy of the blend shows characteristic peaks for both PU and alginate distinctly, indicating good dispersion of both the polymers. pH responsive swelling behavior in different pH media corresponding to the gastrointestinal (GI) tract (pH 1.2 and pH 7.4) are investigated for all the prepared blends. The minimum degree of swelling is observed for PU with maximum amount PEG at pH 1.2, whereas the degree of swelling of the same PU significantly increased at pH 7.4. BSA encapsulation efficiency of the blends increases with an increase in PEG content in the polyurethane and varies within the range of 88-99%. Release profile of BSA at pH 7.4 is found to be similar as observed in swelling stud

    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: 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: 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: 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: 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.
