    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: 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: 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: 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: 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: 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.

    ABSTRACT: Waterborne epoxy acrylate-butylated melamine formaldehyde (EpAc-BMF) coatings and ferrite (Fe3 O4) dispersed nanocomposite (EpAc-BMF-Fe3 O4) coatings have been developed with a view to effectively replace the hazardous solvent borne polymeric coatings. The physico-mechanical properties of these coatings were studied using standard protocols. Electrochemical measurements were made in 3.5 wt% solutions of NaOH, NaCl and HCl as well as in tap water (Cl− ion 63 mg/L; Conductivity 0.953 mS/m). The salt spray test on coated and uncoated MS was carried out in 5 wt% NaCl solution for 600 h. Fe3 O4 nanoparticles in matrix act as filler, which fill the pinhole, interstitial crosslinked spaces and other coating artifacts (micro cracks and voids) regions besides provide strength to the coating material. Electrochemical studies revealed that EpAc-BMF-Fe3 O4 coatings were found to be effective in restricting the penetration of aggressive ions by forming a strong barrier layer at coating metal interface. Among various compositions of EpAc-BMF-Fe3 O4 coatings, EpAc-BMF-Fe3 O4-2.5 coatings have shown highest corrosion protection efficiency in different corrosive media.

    ABSTRACT: The use of reservoirs containing corrosion inhibitors as active substances for corrosion protection is an issue of great interest in the scientific literature. The aim of the present study is to encapsulate quinoline, a corrosion inhibitor, into a micro-reservoir to overcome disadvantages caused by its direct addition into a coating layer. Quinoline incorporated microcapsules with different core solvents were synthesized at room temperature by an interfacial polymerization method. The morphologies, wall structures, particle size and thermal properties of the synthesized microcapsules were investigated. The release study of core material was carried out by loss on drying and UV spectrophotometric methods. The prepared quinoline based microcapsules were incorporated in polyurethane (PU) coatings to study their effect on corrosion of substrate. The anticorrosive performance of coatings loaded with different weight % of microcapsules containing quinoline was tested by immersion of the PU coated mild steel specimens in 5 wt% HCl solution by visual observation and weight loss measurements.

    ABSTRACT: Carbon nanomaterials have been the focal point of intense study in the past few decades owing to its molecularly defined structure, high aspect ratio and extortionate electrical, mechanical and physical properties. In the present study, we report an easy synthesis of carbon nanomaterials from the grass Desmostachya bipinnata. Fresh grass was collected and dried completely under the sun and was subjected to complete incineration in atmospheric oxygen. Scanning electron microscope image reveal the presence of carbon micro- and nanorods in the ash of the burnt grass. Then the ash was treated with piranha solution to obtain carboxyl group on the surface. The surface treatment of the obtained ash was confirmed by infrared spectroscopy and by thermogravimetric analysis. Following the acid treatment, the obtained carboxyl terminated carbon nanomaterials were then reacted with diisocyanate to form amide linkages, which was utilized in the formation of polyurethane films. Minuscle incorporation of ash containing carbon nanomaterial was found to enormously increase the physico-chemical properties of the obtained polyurethane nanocomposite. As compared to the neat polyurethane, the composite material showed a substantial increase in the thermal and mechanical properties.

    ABSTRACT: Results of research on degradation of rubber lining which is the main protection of absorbers in flue gas desulphurization (FGD) systems were presented. The power plant where the system operated is lignite-fired. Owing to measurements using electrochemical impedance spectroscopy and gravimetric determination of water content in the lining, the areas of the system which are most exposed to degradation were shown. The results obtained also allowed for optimization of protections used in absorbers, which resulted in lower density of lining at places with a lower risk of degradation.

    ABSTRACT: In this paper, three bio-based unsaturated polyesters were synthesized from itaconic acid and different diols which could be derived from renewable resources. Their chemical structures were confirmed by FT-IR, 1H NMR and acid value as well as hydroxyl value. Waterborne UV curable networks based on these polyesters were manufactured and their mechanical properties, thermal stability and coating properties including pencil hardness, flexibility, adhesion, water resistance and solvent resistance were investigated. Results showed that the UV-cured polyester coatings exhibited high hardness, good water resistance and solvent resistance. The coatings reported in this paper combined the merits of bio-based materials, UV-curing process and water distribution

    ABSTRACT: Poly(vinylidene fluoride) (PVDF) resins are the dominant component of some of the most weatherable commercially available decorative coatings, which can have color retention and chalk resistance service lifetimes of decades. We have recently oultined a service life prediction model for the decorative properties of coatings of this type (Wood, 2009). The model is based on the “contraction” theory of gloss loss and chalking, coupled with simple assumptions about the photochemical kinetics of two-resin hybrid systems where one resin (PVDF) is much more weatherable than the other (in this case, an acrylic). Because different mechanisms account for gloss loss, color change, and chalking, the relative rates of change for each of these properties can be different, in accordance with experimental observations. In this paper, we combine insights from the model, empirical data from accelerated tests, and long-term weathering test data from solvent-based baked PVDF coatings, to predict the service life of new waterborne no-bake PVDF coatings.
