| Abstract: | Referring to C. N. Nicholas and C. Booth's method, modified polyoxyethylene electrolyte was prepared from polyethylene glycol and dichloromethane. The molecular weight MPK of the obtained polymer was measured by GPC that was greater than 105. The chain structure was characterized by C13NMR which indicated that the polymer was oxymethylene-linked polyoxyethylene. The DSC results of the sample showed that the glass transition temperature Tg~-60℃. the melting point Tm= 11℃,the crystallinity at -20℃ was Xc=26%. The sample appeared as elastomer at room temperature. When it. was dopped with LiCF3SO3 and made into a film, its conductivity at room temperature was measured by method of AC Impedence, that was a = 6×10-5(cm)-1. |
