Solid polymer electrolyte (SPE) is a potential material for the next-generation safe battery system. However, inability of SPEs to maintain mechanical strength and ionic conductivity bottleneck in further research. Here, poly(ether-thioether) with thiol-ene crosslinked network was prepared by situ click polymerization supported on an electro-spun polyimide (PI) mat provide ultrathin membrane (1...

The limited performance of pure glassy and rubbery polymeric membranes for natural gas purification are due to their intrinsic properties. Optimizing properties by blending both polymers expected address the shortage. foremost objective this research is synthesis enhance polymer blend (EPBM) using polysulfone (PSU) polyvinyl acetate (PVAc) with addition amine carbon dioxide (CO2) removal from m...

In the present paper, pure polymeric blend films [PVA: PVP] reinforced by CaCl2.2H2O salt have been produced with different weight ratios (10, 20, 30, 40, 50 wt %) using solution casting method, where mechanical properties such as tensile, hardness, and impact were studied. The effects of ratio on tensile characteristics studied, we note increase in values ​​of that are represented Yung modulus...

AbstractIn the last step of desolvation method for preparation of albumin nanoparticles, glutaraldehyde (GA) is added to stabilize the newly formed nanoparticles. Due to undesirable effects of GA, the objective of this study was to evaluate alternative methods of crosslinking including ultraviolet (UV) irradiation, adding of glucose and combination of both methods. The nanoparticles were prepar...

Fabrication of monodisperse porous polymeric nanospheres with diameters below 500 nm remains a great challenge, due to serious crosslinking between neighboring nanospheres during pore-making process. Here we show how a versatile hypercrosslinking strategy can be used to prepare monodisperse microporous polystyrene nanospheres (MMPNSs) with diameters as low as ca. 190 nm. In our approach, an unr...

Using a new procedure developed in our laboratory for the preparation of thick polymethacrylate films bonded in fused silica capillaries, crosslinked polymeric stationary phases were synthesized in situ in 25-mm-i.d. capillaries. The effect of monomer and crosslinker concentrations on the resulting polymer film Ž . was studied by open tubular capillary electrokinetic chromatography OTCEC Ž . us...
