NOVEL PREPARATION AND PROPERTIES OF NANOCOMPOSITE POLYMER ELECTROLYTES

以含有纳米SiO2的聚乙二醇二丙烯酸酯(PEGDA)为单体,加入液态电解质,通过紫外光辐射固化制备了凝胶态纳米复合聚合物电解质(NCPE).含有纳米SiO2的PEGDA单体是以水性硅溶胶为原料,通过一个溶剂交换过程制备的,与此同时纳米SiO2的表面通过加入甲基丙烯酰氧丙基三甲氧基硅烷(MAPTMS)进行改性,使其表面具有可以参与光固化的丙烯酸酯基团.与用不含纳米粒子的PEGDA单体制备的凝胶态聚合物电解质相比,纳米复合聚合物电解质的电导率更高,尤其是电化学稳定性和界面稳定性有明显提高.
