A cross-linked polyurethane acrylate (PUA) was synthesized by end capping 4,4'-methylene bis(cyclohexyl isocyanate), H 12 MDI/poly-(ethylene glycol), PEG based prepolymer with hydroxy ethyl acrylate (HEA). Significant interactions of the Li + ions with the soft and hard segments of the host polymer have been observed for the PUA complexed with lithium perchlorate (LiClO 4...
The effect of conducting polypyrrole (PPy) on the morphology and ionic conductivity of thermoplastic polyurethane (TPU) doped with LiClO 4 has been described and compared with those of pure TPU system. The TPU–PPy composites were prepared by chemical polymerization of pyrrole inside TPU films. All samples were characterized by their swelling behavior in a liquid electrolyte (LiClO 4 ...
Ionic conductivity and morphology of a two-component hybrid polymer electrolyte comprising a polymer blend, LiClO4 and propylene carbonate (PC) have been studied. The hybrid polymer electrolyte has been made by mixing LiClO4 in required proportions with a blend of thermoplastic polyurethane (TPU) and polyvinylmethylether (PVME) and then adding PC to it. TPU used in this study was a segmented urethane...
