Abstract
AbstractFilms of PEO and PEO blends were efficiently crosslinked by exposure to ultraviolet radiation with high‐pressure mercury lamp. Photochemical crosslinking proceeded in the presence of photoinitiator such as benzophenone or pentaerythritol triacrylate. PEO networks obtained by UV irradiation in the presence of potassium salts (thiocyanate, perchlorate and triflate) as templates showed enhanced cation binding ability for Li+ and Na+ cations. Cationic networks were prepared from crosslinked PEO modified with ethyl methacrylate dimethyl dodecyl ammonium bromide. Stimuli‐sensitive hydrogels (pH and temperature) were prepared from combinations of PEO and poly‐N‐isopropyl acryl amide, polyvinyl methyl ether, polyvinyl acetate and poly‐2‐vinyl pyridine subjected to UV irradiation.
