초록
이온성고분자-금속복합체는 낮은 전압에서도 큰 굽힘 변형을 가져올 수 있는 장점으로 인해 차세대 구동체의 소재로 주목을 받고 있으나, 이온 교환막의 낮은 기계적 물성으로 인해 구동 성능의 한계를 보인다. 본 연구에서는 우수한 기계적 물성을 가지는 엔지니어링 플라스틱인 poly(ether ether ketone)(PEEK)를 개질한 이온 교환막을 도입하여 이러한 한계를 극복하고자 하였다. 술폰화한 PEEK(SPEEK)를 개질시킨 막을 도입하여 구동 성능과 수명이 향상된 구동체를 제작하였다.
Ionic polymer-metal composites are attracting attention as a material for next-generation actuators due to their advantages of large bending displacement at low voltages, but they show limitations in driving performance due to the low mechanical properties of ion exchange membranes. In order to overcome these limitations, modified poly(ether ether ketone) (PEEK), an engineering plastic with excellent mechanical properties, is introduced as an ion exchange membrane. The actuators with improved driving performance and lifetime were fabricated by introducing modified sulfonated-PEEK membrane.
