摘要
设计并合成了丙烯腈-甲基丙烯酸甲酯-甲基丙烯酸聚乙二醇单甲醚酯共聚物及其梳状凝胶聚合物电解质.表征结果表明,合成的产物结构与设计的结果一致.该梳状凝胶聚合物电解质具有丙烯腈和聚氧化乙烯的优点,力学性能优良,室温电导率可达到10-3S/cm,在锂聚合物电池领域中具有实际应用价值.
The copolymer acrylonitrile-methyl methacrylate-poly (ethylene glycol)methyl ether methacrylate and its comb-like gel polymer electrolyte were designed and synthesized. The results indicate that the comblike copolymers with different component ratios have two glass transfer temperatures, one is the main chain's (about 30-60 ℃ ), the other is side chain's( between -50- - 30 ℃ ). The heat stability of the comb-like copolymer changes with variation of the ratios of acrylonitrile. And the copolymer can be used at 150 ℃. The comb-like gel polymer electrolyte takes advantages of acrylonitrile and poly (ethylene oxide). Its mechanical perporties is very good. And the conductivity of the comb-like gel polymer electrolytes is in the magnitude range of 10^-3 S/cm at room temperature. The electrolyte has a value of practical application.
