In this research, different strategies to modify the structure of polymer blends were investigated with the objective of adjusting the composition of polyoxymethylene (POM) and poly(lactic acid) (PLA) under typical processing conditions. POM shows a good balance of mechanical and thermal properties. However, this polymer is obtained from petrochemi...

To prepare a high-performance anti-friction and wear-resistant composite material for friction sub-components in marine equipment, a modification was made by adding different amounts sodium polyacrylate (PAANa) to ultra-high molecular weight polyethylene (UHMWPE). PAANa/UHMWPE-blended powders were prepared at individual weight ratios of 0/100, 3/97...

Optical polyimide (PI) films were prepared by spin-coating from nearly non-volatile dimethylacetamide (DMAc) solutions. The uniformity of film thickness met the requirements of diffraction imaging quality. The results show that the final rotating speed ω, dynamic viscosity η, and initial polymer solid concentration c are the main factors affecting ...

In the current study, surface-modified poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) of brigatinib (BRB) were prepared by studying the variables PLGA (polymer), PVA (stabilizer) and chitosan (coater) against experimentally obtained responses. The optimized NPs (F2) were evaluated in vitro for differential scanning calorimetry (DSC), Four...

Polystyrene/poly(methyl methacrylate) (PS/PMMA) blends in 80:20, 50:50, and 20:80 ratios with and without calcium carbonate nanoparticles were prepared. n-Pentane was then used to foam the samples in an autoclave. After the diffusion of n-pentane gas into the polymer matrix, the samples and the gas were simultaneously cooled to obtain the liquid n-...

Environmental pollution due to heavy metal contamination is a major environmental concern. A fully biodegradable and reusable adsorbent hydrogel for removal of heavy metal ions has been developed. The hydrogel was prepared from acrylic acid and chitosan using an irradiation method. The adsorbent was characterized using Fourier transform infrared an...

In this study, poly(vinyl chloride) (PVC)/acrylonitrile-styrene-acrylic terpolymer (ASA)/acrylonitrile-butadiene rubber (NBR) ternary blends were designed based on the concept of mismatched thermal expansion coefficient between different components, resulting in significant improvement of the low-temperature toughness. The large difference in therm...

Ultra-high molecular weight polyethylene (UHMWPE) composite coatings reinforced with different concentrations (1, 3, 6, and 9 wt%) of submicron tungsten carbide (WC) particles were synthesized using electrostatic sprayed method, characterized and evaluated for corrosion resistance in 1 m HCl electrolytic solution. Results showed that the mechanical...

Traditional injection molding machines use resistance heating (RH) bands to heat the barrel. However, RH has a low energy rate; thus, the time required to reach the target temperature is rather long. Consequently, the use of inductive techniques, with a faster heating rate and improved energy rate, has attracted growing interest in recent years. Ho...

In this paper, the fabrication process of polydimethylsiloxane (PDMS)-based microstructured conductive composites via differential temperature hot embossing was proposed based on the spatial confining forced network assembly theory. The mold temperature was kept constant throughout the whole embossing cycle in this method, whereas the setting tempe...
