그러나 전기활성 고분자의 전극으로는 백금, 금, 금속 합금 등과 같은 여러 가지의 벌크 금속 전극들이 사용되는데 이 들은 너무 고가이고 촉매 작용이 일어나는 표면적을 증가시키기 어렵다. 또한 기존 IPMCs에 재료와 공정 상의 문제로 표면에 크랙이 존재하게 되고, 인가된 전압에 의해 이온성 고분자 층 내의 이온 수화물들이 전기분해가 되며, 금속 전극의 크랙을 통해 증발한다. 또한 인가전압으로 발생되는 열에 의하여 더욱더 수분증발을 더 많이 일어나게 된다. 전극 표면에 결함과 고분자 내부 물 손실은 이온성고분자의 동작 제어를 어렵게 하고, 유연 구동기의 구동 특성을 저하시키며 또한 인가전압의 주파수 범위를 제한하기 때문에, 유연 구동기의 산업적 응용을 크게 방해하는 요소 중 하나이다. 더하여 IPMCs는 구동변위가 큰 데 비해 매우 낮는 구동력을 가지고 있다. 그렇기 때문에 값싼 전극을 사용하는 것과 표면의 crack을 없애는 것이 필요하고, 구동력을 향상시키는 것이 필요하다.However, as the electrode of the electroactive polymer, various bulk metal electrodes such as platinum, gold, and metal alloys are used, which are too expensive and difficult to increase the catalytic surface area. In addition, cracks exist on the surface due to material and process problems in the existing IPMCs, and ion hydrates in the ionic polymer layer are electrolyzed by the applied voltage, and evaporate through cracks in the metal electrode. In addition, more and more moisture evaporation occurs due to heat generated by the applied voltage. Defects on the electrode surface and water loss inside the polymer make it difficult to control the operation of the ionic polymer, degrade the driving characteristics of the flexible actuator, and also limit the frequency range of the applied voltage. It is one. In addition, IPMCs have a very low driving force compared to a large driving displacement. For this reason, it is necessary to use cheap electrodes and to eliminate cracks on the surface, and it is necessary to improve the driving force.

따라서 본 발명은 상기와 같은 문제점을 해결하고자 안출된 것으로, 본 발명에서 제시하는 탄소나노튜브-그래핀 튜브 재료가 적용된 유연구동기의 고분자 층에 삽입하여 구동력 향상과 발생하는 열을 흡수 시킬 수 있을 뿐 아니라, 탄소계 전극만을 이용하여 기존의 금속전극을 대체하고, 금속 못지않은 전자전달 특성을 가지고 있어 우수한 전극으로도 사용 가능하다. 이를 통해 유연구동기의 큰 굽힘 변형을 얻는 동시에 큰 힘을 낼 수 있는 효과를 가지는 금속이 포함되지 않는 탄소나노튜브-그래핀 튜브 재료가 적용된 유연구동기 제조방법을 제공하고자 하는 것이다.Therefore, the present invention has been devised to solve the above problems, and can be inserted into the polymer layer of the research reactor to which the carbon nanotube-graphene tube material proposed in the present invention is applied to improve driving force and absorb generated heat. In addition, it replaces the existing metal electrode using only the carbon-based electrode, and has the same electron transfer characteristics as the metal, so it can be used as an excellent electrode. Through this, it is intended to provide a method for manufacturing a research reactor in which a carbon nanotube-graphene tube material that does not contain a metal having an effect capable of generating a large force while simultaneously obtaining a large bending deformation of the researcher unit is applied.
