| 摘 要： | 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。

| Abstract: | The gel nanocomposite polymer electrolyte (NCPE) was prepared by UV radiation curing based on poly(ethylene glycol) diacrylate (PEGDA) monomer containing nanosize SiO_2 in the presence of liquid electrolyte. The PEGDA monomer containing nanosize SiO_2 was synthesized using aqueous colloidal silica as one of starting materials through a solvent exchange process and the partial surface groups of SiO_2 were modified into acrylic group during the procedure by employing methacryloxypropyl trimethoxysilane (MAPTMS), which made the nanosize SiO_2 having the UV-curable acrylate groups. Compared with the gel polymer electrolyte based on PEGDA without nanosize filler, the ionic conductivity is higher and the improvements in the electrochemical stability and interfacial stability are noticeable for the gel NCPE. |
