摘要： 研究了高分子凝胶电解质高氯酸锂-碳酸丙烯酯-聚甲基丙烯酸甲酯体系(LiClO4-PC-PMMA)的离子导电性、导电机理以及在电色Smart窗中的应用。其离子电导率与温度的关系服从Vogel-Tammann-Fulcher方程,并与体系的PMMA质量百分数、玻璃化温度(Tg)、碱金属盐的浓度等有关。当LiClO4浓度为0.5mol/L,PMMA=35%时,电解质具有良好的粘附性、光学透明度及较高的室温离子电导率(σ=8.75×10-4S/cm).由其组装成的全固态电色Smart窗具有良好的光谱特性,可见光调制范围为40%～60%;具有良好的光开关特性,响应时间仅为5s.

Abstract: The ionic conductivity, conduction mechanism and application to electrochromic Smart windows of polymeric gel electrolyte LiClO4 propylene carbonate polymethyl methacrylate(LiClO4 PC PMMA)have been investigated. The ionic conductivity as a function of temperature followed the empirical Vogel Tammann Fulcher equation and depended on the weight content and Tg of PMMA, and concentration of LiClO4. The electrolyte had a good adhesivity, good transparency and high ionic conductivity at room temperature(σ=8.75×10-4 S/cm), when concentration of LiClO4 was 0.5 mol/L and weight percentage of PMMA was 35%. The assembled electrochromic Smart window had good spectral behavour, at 633.3 nm its optical modulation was 40%～60%. Its optical switching time only 5 s.
