摘　　要：以聚乙二醇甲醚甲基丙烯酸酯(PEGMA)、2-羟基-2-甲基苯丙酮(HMPP)和高氯酸锂(LiClO4)为原料,通过固液研磨和紫外固化的方式制备了基于PEGMA的新型透明凝胶聚合物电解质。通过一系列测试,对凝胶电解质的性能及其应用的电致变色器件性能进行了表征。结果表明,制备的凝胶电解质的可见光透过率达97%,热分解温度为250℃,室温下离子电导率为2. 56×10^-4S/cm以及应用的电致变色器件在660 nm处光学调制幅度达66. 97个百分点。A novel transparent gel polymer electrolyte was prepared by poly( ethylene glycol) methyl ether methacrylate( PEGMA),2-hydroxy-2-methylpropiophenone( HMPP) and lithium perchlorate( LiClO4) by the methods of mortaring and ultraviolet( UV) curing. The properties of the gel electrolyte and its application in electrochromic devices were characterized by a series of tests.The test results show that the prepared gel electrolysis has a visible light transmittance,which could achieve 97%,the thermal decomposition temperature is 250 ℃,the ion conductivity is 2. 56×10^-4 S/cm at room temperature,and the optical modulation amplitude of the electrochromic device( ECD) could achieve 66. 97%at 660 nm.
