Abstract:
Titanium dioxide with coupling agent (ETES) was applied as a photocatalyst for a synthesis of the TiO2/LDPE composite film. The physical properties of TiO2/LDPE composite film were analyzed by a Scanning Electron Microscope (SEM). TiO2 particles were impregnated into the polymer matrix film as a LDPE composite film. The results from the X-ray Diffraction (XRD) technique revealed that the structure of TiO2/LDPE composite film were anatase crystalline. The chemical structure of the TiO2/ LDPE composite films were analyzed by an ATR-Fourier transforms infrared (ATR-FTIR) spectrometer. Wavenumber

Abstract:
LDPE waste disposal is a critical issue nowadays and huge pile of this polymer represents a threat to the environment. Herein, gC3N4/5ZnO/TiO2 photocatalysts (1 wt %) incorporated in LDPE film were investigated and compared with neat LDPE film. Tabletop scanning electron microscopy (SEM) micrograph showed the surface morphologies of neat and LDPE composite films before and after accelerated weathering. Experimental results on LDPE composite films after exposure to UV irradiation showed improvement in degradation rate (~0.274%/hour) in comparison to other study (0.225%/hour). Results of weight

Abstract:
nanoTiO2powders were utilized as thermocatalyst for catalytic degradation of polyethylene in water. LDPE/TiO2composite films were prepared by the method of melt blending. The aging experiments were conducted in ovens under temperatures of 30 °C, 40 °C and 50 °C, respectively. The thermocatalytic degradation behavior towards the composite films was characterized by fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TG) and scanning electron microscopy (SEM). Results show that both pure LDPE films and LDPE /TiO2composite films can be degraded even under low temperatures

Abstract:
Nano-composite films were developed between silver nanoparticles (Ag NPs) and a low-density polyethylene (LDPE) using master batches by melt extruding and melt compounding. The Ag/PE composite film showed decreased gas permeability, moisture permeability coefficient, the tear strength, the longitudinal and transverse elongation to that of commercial LDPE. Although stiffness increased at high Ag (40 ppm) concentration, but the longitudinal and transverse tensile strength enhance comparing with commercial PE. Light transmittance and haze were comparable. Both Nano-silver and composite films are

Abstract:
The growing prevalence of antimicrobial resistance in bacterial strains has increased the demand for preventing biological deterioration on the surfaces of films used in applications involving food contact materials (FCMs). Herein, we prepared superhydrophobic film surfaces using a casting process that involved the combination of low-density polyethylene (LDPE) with solutions containing surface energy-reducing silica (SRS). The bacterial antifouling properties of the modified film surfaces were evaluated using Escherichia coli O157:H7 and Staphylococcus epidermidis via the dip-inoculation tech

Nanocomposites based on low-density polyethylene (LDPE), containing 0.5, 1, 2, 3, and 5 wt% of nanoalumina, were prepared by melt-mixing at 125°C and hot melt-pressing to thin polymer film at 125°C. To enhance the interfacial interaction between alumina and LDPE, alumina surface was treated with silane which acts as coupling agent. The effects of alumina additions to the structure and morphology of LDPE matrix were characterized using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM), respectively.

Abstract New corrosion protective coatings were proposed and long term corrosion tests were performed. These coatings, based on modified polyaniline, showed that hexacyanoferrate improved their anticorrosion properties. Our recent research gives some information about the increasing oxygen diffusivity barrier when nano-TiO2 is added. The goal of this paper was to check if there is a synergy effect between these two compounds. The polyaniline-hexacyanoferrate-nano-TiO2 composites were prepared by in situ oxidative polymerization of aniline in solutions of two different inorganic acids. The corr
