摘要

摘要:采用微乳液法制备杂多酸包埋在纳米二氧化硅基体上。初始粒径小于400nm，随杂多酸含量的增加而减小。当这些二氧化硅颗粒与磺化聚醚砜混合时，HPA在水环境中可以有效地固定化。当HPA浓度为15%时，复合电解质的电导率为1.4×10−3 S/cm。

Preparation of Heteropoly Acid Entraped in Nano Silica Matrix

Abstract Heteropoly acid entraped in nano silica matrix was prepared by the microemulsions method. The primary particle size was less than 400nm and it decreased with the content of the heteropoly acid. When these silica particles were blended with sulfonated polyethersulfone, the HPA could be effectively immobilized in aqueous environment. The conductivity of this composite electrolyte was 1.4×10−3 S/cm with the 15% HPA.
