Abstract
전기활성고분자의 종류 중 하나인 유전성 탄성체의 거동에 대응할 수 있는 유연전극 제조에 대한 연구를수행하였다. 전도성 고분자(PEDOT:PSS)에 가소제 역할을 하는 자이리톨(Xylitol)을 첨가하여 기계적 특성을 평가하였다. 자이리톨을 첨가한 전극의 유연성을 확인하기 위해 실리콘 시편에 전극을 도포하여 인장시험을 수행하였다. 자이리톨을 70 wt% 첨가한 조건에서 연신률이 크게 증가함을 확인하였고 실리콘 거동에 큰 영향을 미치지않는 것을 확인하였다. 또한, 전극과 실리콘의 접착성을 향상시키기 위해 표면조도가 다른 실리콘 필름을 제작하였으며 사포 #120으로 처리한 시편에서 실리콘 필름과 전극의 접착성이 향상됨을 확인하였다.
The fabrication of flexible electrodes coated on the surface of a dielectric elastomer film, which is a typeof electroactive polymer (EAP), was carried out. Controlled amounts of Xylitol powder were added (10, 30, 50 and70 wt%) to the commercial conductive polymer (PEDOT:PSS) to enhance resilience of the electrode. To checkresilience of the fabricated composite electrodes, tensile tests were carried out using silicone films coated with thepolymer electrodes. From the test results, it was found that 70 wt% Xylitol containing conductive polymer hadexcellent elongation and high failure strains. Furthermore, surface of the silicone film was uniformly polished withvarious abrading papers to enhance the wettability of the conductive polymers on the surface of the silicone film. Itwas found that the silicone film polished with #120 abrading paper had the best wettability and guaranteed excellentbonding behavior.
