The objective of this work was to prepare chitosan/polyethylene glycol fumarate (chitosan/PEGF) blend films as wound dressings and to evaluate the influence of composition ratio on the blending properties of the films. Blending chitosan with PEGF obviated the brittleness of neat chitosan film. Film topography performed by atomic force microscopy illustrated that blending could increase and control the surface roughness of the neat film. Their water vapor transmission rates were close to the range of 904-1447 g(-2)day(-1) found to be proper candidates for dressing the wounds with moderate exudates. Controlled water solubility, swelling, wettability and surface tension of the blend films were also evaluated. The blend films showed a powerful antibacterial activity against Pseudomonas aeruginosa and Staphylococcus aureus (Kill%>99.76 ± 0.16%). Physical properties as well as antibacterial activity assessments showed that among different compositions, the film comprising 80 wt% chitosan and 20 wt% PEGF is a suitable candidate for biomedical applications as a wound dressing material.

This study aimed to prepare a composite film by blending cross-linked tapioca starch (CLTS) with sodium alginate (SA), silver nanoparticles (AgNPs), and ZnO nanoparticles (ZnOs). The effects of SA, AgNPs, and ZnOs at different concentrations (1-3 wt%) on the mechanical properties, optical properties, thermal stability, and antibacterial activity of cross-linked starch films were also investigated. The structures of the films were examined by Fourier transform infrared spectroscopy and X-ray diffraction.

The potential of advanced energy storage devices lies in using solid biodegradable polymer electrolytes. This study is focused on a solid blend polymer electrolyte (SBPE) film based on chitosan (CS)-poly (vinyl alcohol) (PVA) blend matrix doped with magnesium chloride (MgCl) salt via solution casting. The interaction of MgCl was verified via X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy.

UV-curable bio-based resins are widely used in the UV curing field. However, the current UV-curable bio-based resins for the application of nail polish still have the problems of too high viscosity and insufficiently excellent mechanical properties. In this study, a soybean oil-based acrylate photosensitive resin is synthesized by using epoxidized soybean oil as a raw material and reacting it with acrylic acid.
