摘要
以对氯甲基苯乙烯/乙烯基苄基氯(CMS/VBC)、甲基丙烯酸甲酯(MMA)、甲基丙烯酸缩水甘油酯(GMA)、1-甲基咪唑(MIm)、双三氟甲烷磺酰亚胺锂(LITFSI)等为原料,通过活性/可控自由基聚合制备了超支化接枝多臂共聚物h-PCMSg-PMMA、功能性嵌段共聚物PMMA-b-PGMA、离子液体嵌段共聚物PMMA-b-PIL-[MIm-TFSI],利用凝胶渗透色谱仪(GPC)、傅里叶变换红外光谱仪(FTIR)、核磁共振氢谱仪(1H-NMR)对其结构进行了确认。再通过溶液共混的方式将上述制备的聚合物混合,得到一系列超支化聚合离子液体共混体系,通过交流阻抗技术对该体系的离子电导率进行了考察。结果表明,离子液体链段PIL-[MIm-TFSI]、超支化结构、PGMA链段的引入均能有效增强该共混体系的离子电导率。
Hyperbranched multi-arm-grafted copolymer h-PCMS-g-PMMA,functional block copolymer PMMA-b-PGMA,and ionic liquid block copolymer PMMA-b-PIL-[MIm-TFSI]were prepared via living/controlled radical polymerization using p-chloromethylstyryl vinyl benzyl chloride,methyl methacrylate,methacrylic acid glycidyl ester(GMA),1-methylimidazole,and lithium bis(trifluoromethylsulfonyl)imide as raw materials.The chemical structures of the resulting products were characterized by;H-NMR,FTIR and GPC.Then,the obtained products were mixed through solution blending to prepare a series of hyperbranched polymer ionic liquid blending systems.Their ionic conductivity was investigated using an AC impedance technology.The results indicated that the introduction of ionic liquid segment PIL-[MImTFSI],hyperbranched structure,and PGMA segment effectively enhanced the ionic conductivity of the blend system.
