| 主权项 | 1. A liner, wherein the liner comprises a PVDF-TrFE (poly(vinylidene fluoride-trifluoroethylene)) copolymer having a crystallinity of over 30%, wherein the PVDF-TrFE copolymer has been annealed for a time period of from 4 to 16 hours, the liner has a permeability ranging from 0 to 60 106·cm3·cm/cm2·s·Pa at a temperature ranging from 12 to 50° C., and a piezoelectric coefficient of the liner is above 15 pC/N. | ||
