(core) By inserting copper nanowire material into the polymer layer of an electroactive polymer flow researcher, it not only improves mechanical properties and absorbs generated heat, but also has a high current density, so it has excellent electron transfer properties. The present invention relates to an electroactive polymer oil-based motivation using a carbon nanotube-graphene core copper nanowire material that can be used as an effective electrode to obtain a large bending deformation of the oil-phase motor while also generating a large force.
최근 몇 년 동안, 전기활성고분자(Electro-Active Polymer, EAP)는 경량성과 신축성 때문에 많은 공학 분야에서 연구되었다. 이온 폴리머 금속 복합체(Ionic Polymer-Metal Composite, IPMC)는 이온전달 특성이 우수한 이온성고분자 전해질 막의 상하 양면에 전자전달 특성이 우수한 금속전극이 입혀진 커패시터 구조로 이루어져 있으며, 낮은 전기 구동 포텐셜과, 큰 변형과 경량으로 가장 인기 있는 전기활성고분자 구동기 중 하나이다. 이러한 이온 폴리머 금속 복합물은 의료용 로봇 구동기, 생체모방 센서 및 인공근육에 적합한 구동기로 많은 연구가 이루어지고 있다. 유연 구동 변위특성을 가지는 IPMC는 낮은 구동전압에 비해 상대적으로 큰 변위를 가지며, 구동기 질량에 비해 큰 전달력을 갖는다. 또한, 변위에 비해 빠른 반응주파수가 출력되며, 공기 중이나 물에서도 구동이 가능하여, 제조공정에 따라 자유로운 형태로 구현할 수 있다. In recent years, electro-active polymers (EAP) have been studied in many engineering fields because of their light weight and elasticity. Ionic Polymer-Metal Composite (IPMC) consists of a capacitor structure coated with metal electrodes with excellent electron transfer properties on both sides of the top and bottom of the ionic polymer electrolyte membrane with excellent ion transfer properties, low electric drive potential, and large deformation. It is one of the most popular electroactive polymer actuators due to its light weight and light weight. Many researches have been conducted on these ionic polymer metal complexes as medical robot drivers, biomimetic sensors, and drivers suitable for artificial muscles. IPMC having flexible driving displacement characteristics has a relatively large displacement compared to a low driving voltage, and has a large transmission force compared to a driver mass. In addition, the reaction frequency is faster than the displacement, and it can be driven in air or water, so it can be implemented freely according to the manufacturing process.

전기활성 고분자의 전극으로는 전기화학적 안정성이 우수한 백금이 주로 사용되는데, 백금 전극은 가격이 너무 고가이고 촉매 작용이 일어나는 표면적을 증가시키기 어렵다. Platinum having excellent electrochemical stability is mainly used as the electrode of the electroactive polymer, and the platinum electrode is too expensive and difficult to increase the surface area where catalysis occurs.
또한, 기존 IPMC에 재료와 공정 상의 문제로 표면에 크랙이 존재하게 되고, 인가된 접안에 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. In addition, cracks are present on the surface due to material and process problems in the existing IPMC, and ion hydrates in the ionic polymer layer are electrolyzed by the applied eye, 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.
그렇기 때문에 값싼 전극을 사용하는 것과 표면의 크랙(crack)을 없애는 것이 필요하다.That is why it is necessary to use cheap electrodes and eliminate cracks on the surface.
