通过原子转移自由基聚合反应(ATRP)合成3种嵌段比不同的聚甲基丙烯酸甲酯-b-聚苯乙烯(PMMA-b-PS),研究其嵌段比例对凝胶聚合物电解质(GPE)电性能的影响.结果发现,以3种嵌段共聚物为基体的GPE导电性均优于纯PMMA基GPE,这可能是因为刚性链段的存在改变了凝胶体系的自由体积；当聚合物含量为40％(质量分数)时,PMMA-b-1PS基GPE的电导率最高.选择电性能较优的PM-MA-b-1PS为基体,研究有机累托石(OREC)对该凝胶电解质(NGPE)性能的影响.在保持凝胶体系固含量为40％(质量分数),OREC添加量为聚合物的3％(质量分数)时,室温下NGPE的电导率达到了3.11×10-4S/cm,约为PMMA基GPE的18倍；热失重分析表明,质量损失5％时,PMMA-b-1PS基GPE热分解温度比PMMA基GPE热分解温度高66.1℃,NGPE的热分解温度相比PMMA基GPE提高了78.0℃.
