Abstract

A solid polymer electrolyte (SPE) with both high ionic conductivity and dimensional stability is essential for air-operating conducting polymer (CP) actuators. In this study, SPE composite was developed by infiltrating polyethylene oxide (PEO), which has high ionic conductivity, into the porous structure of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) film, which offers excellent dimensional stability and high porosity. Based on this composite electrolyte, an air-operating polypyrrole (PPY) actuator was successfully fabricated.


공기 중에서 안정적으로 작동하는 전도성 고분자 구동체의 구현을 위해서는 높은 이온전도도와 우수한 기계적 안정성을 동시에 확보할 수 있는 고체 고분자 전해질의 개발이 필수적이다. 본 연구에서는 이온 전달 특성이 우수한 빗 모양의 폴리에틸렌 옥사이드(PEO)를 우수한 기계적 물성과 높은 기공율을 갖는 poly(vinylidene fluoride-co-hexafluoropropylene)(PVDF-HFP) 필름의 기공 구조에 침투시키는 방법으로 고체 고분자 전해질 복합체를 제조하였다. 이를 기반으로 하여, 공기 중에서도 안정적으로 작동 가능한 폴리피롤(PPy) 구동체를 구현하였다.
