Abstract:
PURPOSE: A composite complex separator is provided to have excellent strength and durability and to improve surface hydrophilicity while maintaining original strength when introducing a hydrophilic functional group. CONSTITUTION: A composite complex separator comprises a support layer which comprises a fluorine-based polymer, and an active layer which comprises polyamide formed on the surface of the support layer. The support layer has a nanofiber web. The fluorine-based polymer is a fluorine-based polymer which is selected from polyvinyl fluoride, polyvinylidene fluoride, polytetra fluoro ethylene, polychlorotrifluoroethylene, fluorinated ethylene-propylene, perfluoroalkoxy polymer, and perfluoro polyoxetane; a copolymer including 50% or more a repeating unit which form the fluorine-based polymer, based on the number of repeating units in a polymer chain; and a polymer blend mixed with 50weight% or more of the fluorine-based polymer.

본 발명은 액체를 이용한 에너지 전환 장치에 관한 것으로, 보다 상세하게는 전기습윤(electrowetting)현상의 반대현상을 응용하여 기계적 에너지를 전기 에너지로 전환시키는 방법 및 장치에 관한 것으로 한쌍의 전극사이에서 액체와의 접촉면을 변화시키고, 그에 따른 액체와의 접촉면 변화를 전기에너지 생성에 활용하여, 채널 막힘현상이나 윤활층, 혹은 채널상에 복잡하게 패터닝된 전극들을 필요로 하지 않도록 함으로써 장치의 단순화, 제조원가 절감과 함께 고장이 적은 에너지 전환장치를 구현한다는 효과가 있으며, 플렉서블 소자 구현이 가능하도록 하고, 소자의 구조를 간단하게 하여 대면적 적용이 용이하도록 한 장점이 있다.
Abstract:
The present invention relates to an energy converting apparatus using liquid and, more specifically, to an apparatus and a method for converting mechanical energy into electric energy by applying the opposition phenomenon to electrowetting. The energy converting apparatus changes a surface in contact with liquid between a pair of electrodes and utilizes the change in the surface in contact with liquid for generating electric energy, so that electrodes complexly patterned on a channel or a lubricating layer are not required or blockage of a channel is prevented. Therefore, the energy converting apparatus can provide less trouble, reduce manufacturing costs, have simplified equipment, make a flexible element, and be easily applied to a large area by simplifying a structure of an element.
