| 摘 要： | 通过将聚氧化乙烯（PEO）分别与表面接枝聚丙烯酸锂和表面接枝二乙二醇甲醚的SiO2微粒共混，制备得PEO／接枝SiO2复合物膜，考察了复合物膜的形态和离子电导性。结果表明：接枝改性增强了SiO2微粒与PEO的相容性，降低了PEO的结晶性，显著提高了复合物膜的室温离子电导率。

| Abstract: | Polyacrylic acid and diethylene glycol monomethyl ether were grafted separately on the surface of fine SiO 2 particles, and then the grafted particles were blended with poly(ethelene oxide)(PEO) to prepare composite polymeric electrolytes. The microstrcucture, conductivities and crystallization of the electrolytes were investigated. Result shows the surface grafting increased the compatibility of the particles with the oragnic phase in comparison with that of clear particles, and the ion conductivity increased, meanwhile the crystallization of PEO was weakened. |
