    ABSTRACT: Terpolymers of aniline, anthranilic acid and o-phenylenediamine/Hydrophilic bentonite composites were synthesized using a 1:1:1 molar ratio of the respective monomers with different percentages of clay via modified in situ chemical terpolymerization. The spectral characteristics upon incorporation of anthranilic acid units into the copoly(aniline o-phenylenediamine) backbone in absence and in presence of bentonite nanoparticles were investigated. Moreover, terpolymer/bentonite composites were thermally more stable than pure terpolymer under nonoxidative condition. On the basis of surface morphological studies of terpolymer composites, a platy network texture can be explained, and it can be clearly seen in the SEM photomicrographs.

    ABSTRACT: The role of nanoclays and TiO2 nanoparticle loadings were investigated on low density polyethylene crystalline structure, in addition to studying packaging film properties such as barrier, thermal and mechanical properties. The polymer crystal study indicated for the orthorhombic crystal phase and about 20% lower degree of crystallinity for nanocomposites containing more than 2 wt.% TiO2 nanoparticles. Based on the X-ray diffraction technique, the dispersion of nanoclays was improved to almost good degree of clay exfoliation with the company of 4 wt.% TiO2 nanoparticles. In agreement with XRD results, the TEM morphological studies mainly suggest that TiO2 has a helpful effect on nanoclay exfoliation. The increase in degradation temperature of nanocomposites may be attributed to the formation of inorganic char on polymer melt. The barrier properties of TiO2/clay nanocomposite packaging films depend mainly on nanoclay loading with an unclear trend from TiO2 nanoparticles. The increase in elastic modulus and the yield stress of nanocomposite films showed great effects on film mechanical properties by nanoclays.

    ABSTRACT: Pure starches do not exhibit fast tacking and high viscosity to meet the standards set by many industrial processes. Therefore, the objective of this work was to obtain high- viscosity coating solutions after modifying tapioca starch with urea as a cross-linker and borax as a thickener. Study of the physical properties confirmed that the prepared solutions were exhibiting more pronounced non-Newtonian behavior. A shear-thinning behavior followed by shear-thickening was observed for all solution compositions. At room temperature, the critical shear rate at which the transition from shear-thinning to shear-thickening occurred was ranging from 45.8 to 78 s−1. However, the shear-thickening response to the applied shear rate was less prominent at higher temperatures. The surface tension and density of the solutions were found to decrease monotonically with an increase in temperature. Once the physical properties were fully understood, 1, 1.5 and 2 mL of each solution were used to coat 30 g of urea fluidized above its minimum level of fluidization. The phenomenological analyses of the coated and uncoated urea samples were carried out by understating their surface morphology, coating thickness, percent coating, dissolution rate, percent release and crushing strength. It was concluded that the coating thickness, percent coating, dissolution rate and percent release increase over time with an increase in solution volume and borax mass; however, some random results were obtained while investigating the effects of the solution volume on the crushing strength. The highest crushing strength was noticed for urea samples coated with 1.5 mL of solution followed by 1 mL, 2 mL and without coating.

    ABSTRACT: Post-industrial waste (PIW) polyamide 6 is successfully used in lieu of commercial virgin polyamide 6, in several automotive applications. The presence of polyamide 66 in the final formulation may affect the mechanical and thermal properties of the PIW polyamide 6 materials. Using unreinforced polyamide 6 from PIW and commercial sources, it was found that the addition of polyamide 66 (below 10 wt.%) lowered the crystallization rate and crystallinity level of all polyamide 6 materials. The thermal and mechanical properties of glass fiber (GF) reinforced PIW polyamide 6 compounds with and without polyamide 66 were also studied. Differential scanning calorimetry (DSC) showed that reinforced materials without polyamide 66 had a higher level of crystallinity. Furthermore, dynamic mechanical analysis (DMA) showed that reinforced compounds without polyamide 66 also had a faster storage modulus buildup immediately after injection molding. Reinforced PIW polyamide 6 compounds without polyamide 66 also exhibited higher tensile and higher vibration weld strengths as well as a thicker heat affected zone (HAZ) than those with polyamide 66, leading to the conclusion that polyamide 66 had a detrimental effect on crystallinity level and consequently on the mechanical properties of GF-reinforced PIW polyamide 6 materials.

    ABSTRACT: Graft copolymerization of styrene and n-butyl acrylate onto enzymatically degraded starch was carried out via surfactant-free emulsion polymerization. The cassava starch was degraded by α-amylase before copolymerization, which greatly enhanced the starch content in copolymer. A series of latexes with small particle size, narrow size distribution, and high stability were prepared. The effect of starch degradation on graft copolymerization was investigated. High grafting efficiency was obtained. The application test of the latex showed that the surface strength of coated paper was improved, and all the other properties are very close to those of paper coated with conventional styrene-acrylate latex.

    ABSTRACT: Terpyridine containing thiophene monomer was synthesized. Electrochemical behavior of the monomer was studied by cyclic voltammetry. This monomer was polymerized via electrochemical methods and the resultant polymer was characterized. The stepwise fabrication process of the polymeric film electrode and its electrochemical sensing performance towards simultaneously Co and Cu ions were evaluated. The sensing parameters of the polymer electrode were investigated in detail, and the determination conditions were optimized. Under the optimal conditions, sensor response peak is linear to the Co ion concentration in the range of 1.0-50.0 µM and the Cu ion concentration in the range of 1.0–20.0 µM. Detection limit of terpyridine-based polythiophene film electrode for Co and Cu is respectively 100 nM and 0.05 nM.

    ABSTRACT: In the present study nanocomposite fibers and film scaffolds based on poly (2-hydroxy ethyl methacrylate) and microcrystalline cellulose were prepared by electrospinning method and solvent casting method, respectively. Paclitaxel (20 ppm) was incorporated during the preparation of fibers and film to result in paclitaxel-incorporated nanocomposite film and fibers with an encapsulation efficiency of 63% and 72%, respectively. These prepared nanocomposite films and fibers were characterized and confirmed by FTIR, XRD and SEM analysis. The biocompatibility of the nanocomposite scaffolds were assessed using VERO cell lines. The in vitro release of paclitaxel from the nanocomposite fibers, and film was found to be 74 ± 1.2% and 64 ± 1.2%, respectively.

    ABSTRACT: Novel cross-linked polysiloxane with end-capped epoxy groups as waterproofing agent for fabric was synthesized by hydrosilylation of polymethylhydrosiloxane and an epoxy groups-terminated polyvinylmethylsiloxane, which was previously prepared via anionic ring-opening polymerization of octamethylcyclotetrasiloxane, 2, 4, 6, 8-Tetramethyl-2, 4, 6, 8-tetravinylcyclotetrasiloxane, and epoxy group-terminated polydimethylsiloxane using tetramethylammonium hydroxide as a catalyst. Synthesis parameters were discussed in detail. Fourier transform infrared spectroscopy and nuclear magnetic resonance spectra confirmed structure of the resultants. X-ray photoelectron spectroscopy analysis further verifies that the cross-linked polysiloxane film was indeed covered on cotton surface. Thermal stability of those polymers was improved with augment of the cross-linking degree.

    ABSTRACT: Starch/PVA/CaCO3 nanobiocomposite films were prepared by the solution casting method. The prepared nanobiocomposite films were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and selected area electron diffraction (SAED) methods. The fire retardant, tensile strength and thermal properties of nanobiocomposite films were enhanced with increasing percentage of CaCO3. When the concentration of nano-CaCO3 was increased, the oxygen permeability of starch/PVA/CaCO3 was reduced. The increase in fire retardant and oxygen barrier properties along with improvement in thermal and tensile properties of nanobiocomposite may enable the material suitable for packaging application.

    ABSTRACT: In this study, the copolyesters based on 4-hydroxybenzoic acid (HBA) and vanillic acid (VA), lactic acid (LA) and poly(butylene terephthalate) (PBT) were synthesized via melt polymerization and fully characterized by various measurements. The influences of content of HBA and VA units on thermal behavior, structure and degree of crystallinity of copolyesters were discussed in more detail. It was found that the copolymerization of aliphatic and aromatic units together could make the best use of advantages of the respective polyesters. Moreover, the copolyesters with more than 40 mol% of HBA and VA units could show liquid crystallinity in broad temperature range.

    ABSTRACT: Polyurethane nanocomposites were synthesized using one-step solution polymerization of poly(3-hydroxybutyrate)-diol, poly(butylene adipate)-diol using 1,6-hexamethylene diisocyanate. Nanocomposites were prepared using an in-situ polymerization method. The structure was verified using FTIR and 1HNMR. Morphology was examined by XRD and TEM methods. Thermal properties were examined using DSC and TG. DSC showed that all samples were semicrystalline. The Cloisite 30B enhanced the melt crystallization of PHB segments while hindering those of the PBA segments. Thermal stability was improved compared to the neat PUs samples. The Coats-Redfern model was used to calculate the activation energy. Mechanical properties were improved with incorporation of organoclays.

    ABSTRACT: Low-density heat resistamt, low-cost polystyrene (PS)/graphite microspheres were successfully synthesized via in situ suspension polymerization. Scanning electron microscopy (SEM) indicated that PS/graphite composite microspheres had good sphericity, and graphite particles were evenly dispersed in microspheres. Furthermore, density analysis illustrated that the density of composites was about 1.025–1.185 g/cm3 with good suitability for carrying water. Thermodynamic testing revealed that the thermostability of the composite was dramatically improved by the introduction of graphite, which is used deep underground. In addition, the percentage of damage decreased to 1.3% with graphite ratio of 2.5% at 68 MPa. Therefore, PS/Graphite composite microspheres possess entirely feasible applications in oil exploitation as pure water carrying petroleum proppants.

    ABSTRACT: An improved toughness-stiffness balance was achieved in PBT matrix by adding poly(n-butyl acrylate)/poly(methyl methacrylate-co-glycidyl methacrylate) (PBMG) core-shell structured copolymer.A series of poly(n-butyl acrylate)/poly(methyl methacrylate-co-glycidyl methacrylate) (PBMG), core-shell structured modifiers with different contents of functional monomer (glycidyl methacrylate) were prepared, and the effects on mechanical properties of poly(butylene terephthalate) (PBT) blends were investigated. The morphology of the core-shell structure was confirmed by means of transmission electron microscopy. Scanning electron microscopy was used to observe the morphology of the fractured surfaces. The dynamic mechanical analyses of PBT/PBMG blends showed two merged transition peaks of the PBT matrix, with the presence of PBMG core-shell structured modifier, which were responsible for the improvement of PBT toughness.

    ABSTRACT: Multiwall carbon nanotubes (MWCNT)s-reinforced poly(ester-imide)s (PEI)s composites were synthesized under sonication. Step-growth polymerization of amino acid based diacid with 4,4′-thiobis(2-tert-butyl-5-methylphenol) was carried out to give a chiral PEI. S-Valine amino acid was covalently attached to carboxylated MWCNTs by an amide bond and effectively dispersed in aromatic polymer as a continuous medium to prepare PEI/MWCNT composites. Microscopic observations showed that the dispersion of the CNTs was improved by the amino acid groups on the surface of MWCNTs and functional groups on the PEI. In comparison with the neat PEI, the MWCNTs reinforced composites revealed higher thermal stability.

    ABSTRACT: A new nanostructure poly(amide-imide) (PAI) was prepared from the polymerization of 4,4′-methylenebis(3-chloro-2,6-diethyl trimellitimidobenzene) as a diacid with 3,5-diamino-N-(4-hydroxyphenyl)benzamide using triphenyl phosphite as a condensing agent and tetra-n-butylammonium bromide as a green media. The synthesized polymer was used to prepare PAI/ZnO nanocomposites (PZNC)s using nano-ZnO surface-coupled by N-trimellitylimido-L-alanine diacid as a coupling agent through ultrasonic process. The resulting PZNCs were also characterized by FT-IR, powder X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and thermogravimetric analysis (TGA). The TEM and FE-SEM results showed a good dispersion of nanoscale inorganic particles in the polymer matrix.

    ABSTRACT: A series of polyurethane elastomers with enhanced thermal stability was prepared and their physical and thermal properties were studied. For this purpose in the first step, an excess amount of methylene diphenyl diisocyanate was reacted with poly(tetramethylene ether) glycol to produce isocyanate-terminated polyurethane pre-polymer. In the second step, a new imide-based diol chain extender was synthesized via reaction of benzophenonetetracarboxylic dianhydride with 5-amino-1-naphthol. Finally, reaction of the pre-polymer with chain extender resulted in preparation of polyurethane elastomers. Presence of imide unit in the polymer backbone improved their properties and enhanced thermal stability of polyurethane.
