摘要
以甲基丙烯酸甲酯(MMA)和丙烯腈(AN)为单体,自由基引发聚合合成了聚(甲基丙烯酸甲酯-丙烯腈)[P(MMA-AN)]无规共聚物。采用红外光谱分析及元素分析法对共聚物的结构进行了表征。然后以此P(MMA-AN)无规共聚物为基体制备共聚物含量分别为30%、40%、50%(质量分数)的凝胶聚合物电解质(GPE)。采用交流阻抗法对其电性能进行表征。结果发现当MMA与AN投料比为1:3且共聚物在凝胶聚合物电解质中质量分数为30%时,GPE体系电导率达到最大值。
Random copolymers P（MMA-AN） were synthesized by free radical polymerization,where methyl methacrylate （MMA） and acrylonitrile （AN） were used as monomers.The structure of the copolymers were characterized by Fourier transform infrared （FTIR） and elementary analysis.The membranes of polymer electrolyte based on the above P（MMA-AN） copolymers have been successfully prepared by solution casting technique separately.A series of polymer electrolytes containing copolymers with a mass fraction of 30%,40% and 50% were prepared and their ion conductivity was characterized by AC impedance.As a result,the ion conductivity of GPE system reaches a maximum value when the molar ratio of MMA and AN is 1：3 and the mass fraction of copolymer is 30%.
