摘要
采用α 烯丙基聚醚(UPEO)/烯丙基磺酸锂(LS)/苯乙烯(St)共聚反应,合成得到一种以聚烯烃链为主链、侧挂聚醚和烷基磺酸锂的新型单离子梳状聚合物电解质(CPPL)。通过元素分析、IR、GPC以及DSC等对其结构与形态进行了分析表征。研究了反应物料配比、催化剂、反应时间等因素对CPPL物理性能的影响。研究结果表明:该类聚合物电解质膜材料的θg值和成膜性能主要取决于单体原料配比,CPPL室温电导率可达9.3×10-3s/cm。
A kind of novel comb-like single ionic polymer electrolyte(CPPL) suspending short chain polyether and lithium sulfonate was designed and synthesized by the copolymerization of styrene,α-allyl polyether and lithium allylsulfonate.The micro-structure has been determined through EA、IR,GPC and DSC.The conductivity,thermo-stability,electrochemical stability and film intensity have also been investigated.The experimental results indicate the conductivity reached 9.3×10^(-3) s/cm at room temperature.
