Abstract

A new polymeric electrolyte with mobile charges of one type has been synthesized. It is a block copolymer with non-ionic block of poly(2,2,3,3,4,4,5,5-octafluoropentyl methacrylate), which improves mechanical performance, and ionic block as a random copolymer of lithium 1-[3-(methacryloxy)-propylsulfonyl]-1-(trifluoromethanesulfonyl)imide with poly(ethylene glycol) methacrylate. A possibility has been shown for the tuning of ionic conductivity in a wide range (from 1 × 10^–10 to 1 × 10^–7 S cm^–1, 25°C) by varying the ratio of macromolecular weights of neutral and ionic blocks and concentration of lithium monomer units in the ionic block.

新型锂导电共聚物的合成及其结构和组成对离子电导率的影响

合成了一种具有单一类型移动电荷的新型聚合物电解质。它是与非离子嵌段的聚(2,2,3,3,3,4,4,5,5 -辛基氟戊基甲基丙烯酸酯)嵌段共聚物，提高了机械性能，离子嵌段为1-[3-(甲基丙烯氧基)-丙基磺酰基]-1-(三氟甲烷磺酰基)亚胺与聚(乙二醇)甲基丙烯酸酯的无规共聚物。通过改变中性块和离子块的大分子质量之比以及离子块中锂单体单元的浓度，有可能在宽范围内(从1 × 10-10到1 × 10-7 S cm-1, 25°C)调节离子电导率。
