摘要
本工作合成了甲基丙烯酸齐聚氧化乙烯酯(MEO_n)和甲基丙烯酸已磺酸锂(SHMLi)两种单体,基于这两种单体制备了一系列具有单一锂离子导电性的共混络合物;讨论组分聚合物结构,极性基、制样方法等因素对共混络合物凝聚态结构和锂离子导电性的影响;通过在位聚合法制备了室温下锂离子电导率为2.5×10^(-6)S/cm 的共混络合物.
Synthesized were both oligo (oxyethylene) methacrylates (MEO_n) andlithium methacryloyl hexylsulfonate (SHMLi),from which a series of blendcomplexes with single-Li^+-ionic conduction was formed.The effect of polyme-ric structure,polar acrylonitrile group and preparing method on Li^+-ionicconductivity of the blend complexes was investigated.The results show that thebetter the compatibility of two component polymers,the higher Li^+-ionic condu-ctivity.An optimum Li^+ ionic conductivity of 2.5×10^(-6)S/cm at 25℃ wasobtained for the blend complex P(0.6MEO_(18)-0.4AN)/P(0.5SHMLi-0.5AN)prepared by means of in situ polymerization.
