초록
단일벽 탄소나노튜브와 전기전도성 폴리머로 구성된 복합재 엑츄에이터의 변형율-전압간의 관계식이 유도되었으며, 얇은 복합재 필름 형태의 엑츄에이터의 전기기계적인 작동을 수식화하기 위해서 전기화학적 이온 접근법을 사용하였다. 이 방법은 엑츄에이터의 작동에 대한 이해를 쉽게 할 수 있다. 실험결과와 계산결과는 잘 일치한다. 이상적으로 잘 배열된 단일벽 탄소나노튜브 엑츄에이터는 좋은 반응특성과 작동력을 나타내었다. 작동변위는 나노튜브와 기지인 폴리머의 영향을 받으며, 단일벽 탄소나노튜브는 양의 전압에서는 기지를 보강하며 음의 전압에서는 기지를 수축하게 하는 영향을 미친다. 나노튜브의 배열을 곧게하고, 적절한 전해질과 전압을 선택하면 엑츄에이터의 성능을 최적화시킬 수 있다.
Abstract
The relationship between strain and applied potential was derived for composite actuators consisting of single-wall carbon nanotubes (SWNTs) and conductive polymers (CPs). During deriving the relationship, an electrochemical ionic approach is utilized to formulate the electromechanical actuation of the composite film actuator. This relationship can give us a direct understanding of the actuation of a nanoactuator. The results show that the well-aligned SWNTs composite actuator can give good actuation responses and high actuating forces available. The actuation is found to be affected by both SWNTs and CPs components and the actuation of SWNTs component has two kinds of influences on that of the CPs component: reinforcement at the positive voltage and abatement at the negative voltage. Optimizations of SWNTs-CPs composite actuator may be achieved by using well-aligned nanotubes as well as choosing suitable electrolyte and input voltage range.
