Abstract
For a new double comblike ion conducting solid polymer electrolyte, bis[2-(2-methoxyethoxy)ethyl]itaconate (bis(MEE)itaconate) monomer was prepared from itaconic acid and 2-(2-methoxyethoxy)ethanol. The ion conducting polymer films were prepared by photoinitiated radical polymerization of bis(MEE)itaconate, diethyleneglycol dimethacrylate and LiClO4 with benzoin methyl ether(BME) as a photoinitiator. The plasticized polymer gel electrolytes were also prepared by photopolymerization in the presence of ethylene carbonate/propylene carbonate. EC/PC (1/1, 70 ~ 150 mol%) as a plasticizer, 5 ~ 10 % of crosslinker and concentration of alkali salt [EO]/[Li+]=10/1, 8/1 and 6/1 were used The optimum [EO]/[Li+] ratio for high ion conductivity was found to be 8. The crosslinked polymer gel alkali salt complexes showed ion conductivity 5.6 x 10-6 S/cm and the EC/PC plasticized polymer gel electrolytes showed ionic conductivity 3.6 x 10-4 S/cm. They showed a rubber elasticity and maintained a mechanical stability as a free standing film.

새로운 종류의 이중 측쇄 이온배위능을 가지는 고분자 고체 전해질을 제조하기 위해서 bis(MEE)itaconate 단량체를 2-(2-methoxyethoxy)ethanol과 itaconic acid를 에스테르화 반응하여 합성하였다. 이온전도성 고분자 필름은 bis(MEE)itaconate, diethylene glycol dimethacrylate 그리고 LiClO4의 혼
