Аннотация: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.
