Solid solutions of low molecular weight of poly (ethylene oxide) and lithium perchlorate conductivity, glass transition temperature and ftir studies / Ainnur Izzati Kamisan

Solution casting technique served to prepare solid solutions of low molecular weight of poly(ethylene oxide) (PEO) and lithium perchlorate (LiC104) with PEO having different molecular masses (M1] = 6, 10, 20 kg mol"1 ). Salt concentrations (Y) of the solutions were varied between around 0.02 an...
