Sodium alginate (TiO2) sand composites were prepared by solution casting. Purified sand was added in the composite films to increase electrical conductivity. Electrical properties such as conductivity, capacitance, dielectric constant, and loss tangent of the composites were investigated. The current voltage characteristics for all the composites showed ohmic behavior. All the electrical proper...

Nowadays, there is a growing interest to develop biodegradable functional composite materials for food packaging and biomedicine applications from renewable sources. Some composite films were prepared by the casting method using chitosan (CS) and agarose (AG) in different mass ratios. The composite films were analyzed for physical-chemical-mechanical properties including tensile strength (TS), ...

Chemical cross-linking modification can significantly enhance the tensile strength (TS) of soy protein isolate (SPI)-based composites, but usually at the cost of a reduction in the elongation at break (EB). In this study, eco-friendly and high-potential hybrid SPI-based nanocomposites with improved TS were fabricated without compromising the reduction of EB. The hybrid of carboxymethylated chit...

The present study was conducted to develop a nanocomposite film of carboxymethyl cellulose (CMC) reinforced with nanocrystals isolated from microcrystalline (CNCMCC) in the presence bismuth ferrite (BFO)/poly-o-phenylenediamine (PoPD). physicochemical properties, mechanical and thermal stability, its photocatalytic activity towards removal methyl orange (MO) were determined. Results show that i...

Gelatin films were prepared by casting. Tensile strength (TS) and elongation at break (Eb) of the gelatin films were found to be 46 MPa and 3.5%, respectively. Effect of gamma radiation (Co-60) on the thermo-mechanical properties of the gelatin films was studied. 2-hydroxyethyl methacrylate (HEMA) was added to the gelatin during casting varying (10% 30% by weight) and found to increase the TS s...

Anion exchange membranes are highly versatile and nowadays have many applications, ranging from water treatment to sensing materials. The preparation of anion exchange membranes (AEMs) from brominated poly(2,6-dimethyl-1,6-phenylene oxide) (BPPO) and methyl(diphenyl)phosphine (MDPP) for electrodialysis was performed. The physiochemical properties and electrochemical performance of fabricated me...

During the long-term operation of high-voltage cross-linked polyethylene (XLPE) cables, cable will gradually deteriorate under effect various aging factors. Thermal is one key factors directly related to reliability XLPE cables. In this paper, thermal samples are prepared for PDC measurement. Based on polymer trap theory and extended Debye model, shape curve, depolarization charge, parameters f...

Sodium alginate films at various concentrations of glycerol (0.4, 0.6, and 0.8% v/v) were prepared characterized. The thickness, water solubility (WS), vapor transmission rate (WVTR), tensile strength (TS), elongation break (EB) Young’s Modulus (YM) the affected by amount added. Among these films, film containing lower (0.4 % presents better WS, WVTR, highest TS compared to other concentrations...

Blend film of polyvinyl alcohol (PVA) based gelatin was prepared by mixing aqueous solutions of both samples. The mixed aqueous solutions of both samples in different ratios (P1, P2, P3, P4 and P5) were then cast onto silicon paper covered glass plate to form film. These films were then irradiated under gamma radiation (60Co) with different intensities (total dose) like 50, 100, 150, 250 and 50...
