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?PCMS?g?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。

Abstract:

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 polymeri?zation 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 1H?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?[MIm?TFSI], hyperbranched structure, and PGMA segment effectively enhanced the ionic conductivity of the blend system.

Key words: hyperbranch, multi?arm?grafted copolymer, block copolymer, free radical polymerization, solution blending, ionic conductivity
