    ABSTRACT: Hydrazones are present in many of the bioactive heterocyclic compounds that are of wide interest due to their biological applications. This article focuses on the synthesis of the hydrazone ligand and its metal complexes and their potential application as anti-microbial, antifouling and flame retardant additives in epoxy formulations for surface coating application. Selected divalent (CoII) and trivalent (CrIII and FeIII) metal complexes of arylhydrazones, namely o-hydroxyacetophenone benzoylhydrazone (HBH) have been isolated and characterized by a combination of elemental analysis, FTIR, 1HNMR and mass spectra. The ligand and its metal complexes were physically added to an epoxy resin. Experimental coatings were produced on a laboratory scale, and then applied using a brush onto both wood and steel panels. Results obtained from an oxygen index value indicated that the epoxy resin containing the ligand (HBH) and its metal complexes as additives, exhibit a very good flame retardancy effect. The results of the biological activity indicated that the HBH ligand and its metal complexes exhibit a very good antimicrobial and antifouling effect, with the metal complexes showing better results than the ligand. Both physical and mechanical resistance properties were also studied, to evaluate any drawbacks due to the inclusion of the additives. The additives did not affect the flexibility, hardness and adhesion of the epoxy resin formula. The gloss was increased due to the incorporation of the aromatic ring, and the impact strength was also increased due to the incorporation of metal into the epoxy resin formulation.

    ABSTRACT: Polyimide/titania (PI/TiO2) nanocomposite films have been successfully fabricated through the in situ formation of TiO2 within a PI matrix via sol–gel method. Poly(amic acid) (PAA), which is the precursor of PI, was successfully synthesized by mixing pyromellitic dianhydride (PMDA), with equimolar amount of a diamine monomer having a pendent benzoxazole unit and two flexible ether linkages in N,N-dimethylformamide (DMF) solvent. Tetraethyl orthotitanate [Ti(OEt)4] and acetylacetone were then added to the resulted PAA. After imidization at high temperature, PI/TiO2 hybrid films were formed. The structure and morphology of the hybrid nanocomposites with different titania contents (0 wt%, 5 wt%, 10 wt%, and 15 wt%) were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, and transmission electron microscopy. The results indicate that the TiO2 nanoparticles were homogeneously dispersed in the hybrid films. The thermogravimetric analysis of nanocomposites confirms the improvement in the thermal stability with the increase in the percentage of titania nanoparticle. Transmission electron microscopy showed that the nanoparticles with an average diameter of 25–40 nm were dispersed in the polymer matrix.

    ABSTRACT: A new method named two-step emulsification process was developed to synthesize high solid content waterborne polyurethanes by strict control of the bimodal particle size distribution. In the first step, a series of 40% solid content polyester-based (WPU-1) with low content of hydrophilic group and large particle size were firstly synthesized. In the second step, polyether-based prepolymers (WPU-2 prepolymers) with high content of hydrophilic group were firstly prepared and WPU-1 emulsions were used to emulsify WPU-2 prepolymers to obtain the final emulsions with high solid content (WPU-3). The particle size of WPU-3 present bimodal distribution and the diameter ratio and volume percentage of large particles to small particles in WPU-3 were able to be strictly controlled by this method. The viscosity of WPU-3 with 55% solid content was only 489.1 mPa s−1 when the diameter ratio of large particles to small particles was 9.2 and the volume percentage of large particles was 74%.

    ABSTRACT: Polymerized solid-type urushiol (YPUOH) with high thermal stability and excellent antimicrobial properties was prepared and incorporated into low-density polyethylene (LDPE) via melt-compounding and subsequent melt-extrusion processes. To investigate the feasibility of as-prepared LDPE/YPUOH composite films for use in packaging applications, the films were characterized as a function of YPUOH using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (WAXD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), contact angle, and antimicrobial activity assays. The physical properties and antimicrobial activities were found to be strongly dependent upon the changes in chemical and morphological structures originating from different compositions of the composite films. The thermal stability of the composite films was effectively improved with YPUOH addition. Incorporating YPUOH caused the water vapor transmission rate (WVTR) to decrease from 10.3 to 6.5 g/m2·day, suggesting that the barrier properties of LDPE, which are relatively good per se, were further improved. Furthermore, the LDPE/YPUOH composite films exhibited good antimicrobial activities against both Gram-negative and Gram-positive micro-organisms. However, the dispersion of YPUOH in the LDPE matrix was not satisfactory due to a weak interaction between LDPE and YPUOH, which may adversely affect the thermal and barrier properties at higher contents of YPUOH. Further studies are required to increase the compatibility and dispersion of YPUOH in the LDPE matrix in order to optimize its performance and expand its applications.

    ABSTRACT: Optically anisotropic films by shear coating of a lyotropic chromonic liquid crystal (LCLC) aqueous solution were developed on a triacetyl cellulose (TAC) film instead of a glass substrate. The TAC film surface was treated using a sodium hydroxide (NaOH) solution to increase its surface energy for wetting ability. Although the desired surface energy, which is competitive with glass, was achieved, the TAC film surface became rougher during NaOH hydrolysis, which aggravated the alignment of LCLC aggregates, especially for those with a small length-to-width ratio. To alleviate the surface roughness without compensating the surface energy, further treatment of the NaOH-hydrolyzed TAC film was performed using atmospheric pressure Ar/O2 plasma. After optimization of the treatment conditions, the combined method could enhance the polarization efficiency (Peff) of the anisotropic film on the TAC substrate from 91.2% to 95.9%, which was nearly equal to that on a glass substrate.

    ABSTRACT: To enhance the thermal stability and barrier properties of pure poly(vinyl alcohol) (PVA), five different cross-linked poly(vinyl alcohol)/boric acid (PVA/BA) hybrid films were prepared via a solution blending method, and their properties including barrier properties, thermal stability, transparency, and mechanical properties were investigated as a function of the BA content. The physical properties of the PVA/BA hybrid films were strongly dependent upon the chemical structure and morphology of the films originating from the amount of BA and change in degree of cross-linking. With increasing BA content, the size and amount of PVA crystallites decreased, whereas the cross-linking density increased, resulting in more compact packing of the molecules and lower free volume in the amorphous regions. The glass transition temperature and thermal stability were highly enhanced with increasing BA content. The oxygen transmission rate (OTR) of pure PVA decreased from 5.96 to 0.15 cc/m2 day with increasing BA content and were greatly suppressed by 22.8% for 1% BA, 7.7% for 3% BA, and 2.5% for 3% BA, respectively, relative to pure PVA film. With increasing BA content, their water-resistant pressure and tensile strength increased with BA loading. All the hybrid films showed good transparency. These properties of the cross-linked PVA/BA hybrid films make them potential candidates for versatile applications as coatings, films, and packaging materials.

    ABSTRACT: The present investigation reports the preparation and characterization of the thermally stable poly(vinyl alcohol)/(poly(amide-imide)-SiO2) nanocomposite (PVA/PAI-SiO2 NC) films. For this reason, the surface of SiO2 nanoparticles (NPs) was modified with N-trimellitylimido-l-methionine and subsequently, 5 wt.% of modified SiO2 NPs were dispersed in the PAI matrix via sonochemical reaction. The resulting NC was studied by different techniques. Finally, the PAI-SiO2 NC was employed as nanofiller and was incorporated into the PVA matrix for the enhancement of its mechanical and thermal properties. The synthesized NCs were studied by Fourier transform infrared and X-ray diffraction spectroscopy analysis. The surface topography and morphology of the NCs were studied by atomic force microscopy techniques, field emission scanning electron microscopy and transmission electron microscopy. The micrographs demonstrated that the nanofillers were homogeneously dispersed in the PVA matrix. The thermo gravimetric analysis curves indicated that the thermal decomposition of the PVA/PAI-SiO2 NC films shifted toward higher temperature in comparison with the pure PVA. The effect of nanofiller on the mechanical properties of NC films was also explored.

    ABSTRACT: A series of UV curable EA-Si hybrid coatings were prepared by a simple approach combining radical and cationic photopolymerization, with epoxy acrylate (EA) as monomer, γ-glycidoxypropyltrimethoxysilane (GPTMS) as inorganic precursor, benzophenone (BP) as free radical photo initiator and a diaryliodonium salt DPIHFP as cationic photo initiator. The chemical structures of EA-Si hybrid coatings were characterized by Fourier transform infrared (FTIR), Raman spectroscopy and X-ray diffraction (XRD). The thermal and optical properties of hybrid coatings were investigated by thermal gravimetric analysis (TGA) and UV–vis transmission spectroscopy, respectively. The results indicated that cross-linked network structure of SiOSi formed in the hybrid coatings, which led to the decrease in crystallinity and of EA-Si hybrid coating. The final conversion of CC bonds was also decreased because of the addition of GPTMS. The thermal stability of EA-Si hybrid coatings was enhanced in the second decomposition stage (300–400 °C) because of the existence of organic–inorganic cross-linked network structures. The transparency of coatings at around 346 nm tended to increase with increasing concentration of inorganic precursor GPTMS.

    ABSTRACT: In the current study, nano-clay was incorporated in toughened epoxy modified with epoxidized soybean oil (ESO) to improve the mechanical and thermal properties. Curing behavior was studied by Fourier Transform Infrared spectroscopy and Differential Scanning Calorimetry analysis to investigate the effect of ESO bioresin and nanoclay on cross-linking reaction. The increase in enthalpy of curing reaction and decrease in peak temperature of nanocomposite corroborated the catalytic effect of clay on the curing process. The thermal stability parameters like integral procedural decomposition temperature and decomposed activation energy were determined using Horowitz and Metzger equation. Dynamic mechanical analysis demonstrated the high storage modulus, improved crosslink density and good damping behavior of nanocomposite. Thermo mechanical analyzer was used to examine the coefficient of thermal expansion (CTE) of bio-based epoxy blend and nanocomposite in both glassy and rubbery region. The CTE value is decreased after addition of clay to the modified epoxy blend which confirmed the improved dimensional stability of the nanocomposite. TEM and X-ray diffraction analysis confirmed both intercalated and exfoliated clay platelet within the epoxy blend.

    ABSTRACT: One of the common additives in water base coating formulation is antibacterial agents. By increasing environmental restrictions about toxic additive and materials, using sustainable materials in coatings formulations is strongly recommended. This research work introduces chitosan biopolymer as a biocompatible antibacterial additive in cathodic electrodeposition bath. The effect of chitosan concentration in electrocoating formulation was studied. Chitosan solutions in different solid content were prepared in lactic acid and were added to formula. The electrodeposition process and final films were investigated by optical microscopy and Pierce film growth model. It was found that chitosan concentration has a significant influence on the chitosan solution structure in bath and final electrodeposited films. The results show that 0.125% v/w concentration has a suitable antibacterial activity and make acceptable electrodeposited film.
