Abstract
An alternating copolymer-based poly(ionic liquid) (PIL) was synthesized and blended with PVDF-HFP to obtain solid-state polymer electrolytes with both high mechanical strength and high ionic conductivity. Structural analysis reveals that the high performance is attributed to the nanophase separation of PVDF-HFP with a PIL in the nanometric scale, which benefits from an alternating polymer architecture of the PIL.
