摘要:

電流變液是一種電響應(yīng)智能材料，由微納米尺寸的介電顆粒分散在絕緣油中組成。從發(fā)現(xiàn)到現(xiàn)在的70余年中，雖然出現(xiàn)了種類繁多的電流變液，但是由于存在力學(xué)性能、沉降性能、再分散性能、零場粘度和電流密度等方面的問題，制約了電流變液在實際工業(yè)中的應(yīng)用。巨電流變液的出現(xiàn)在一定程度上推進了電流變液的發(fā)展，但距離實現(xiàn)真正的工業(yè)化還有一些問題有待解決。本文主要從電流變液分散相，連續(xù)相和添加劑三方面介紹了近期的研究成果，著重介紹了近期出現(xiàn)的四類具有代表性的顆粒。并簡單總結(jié)了電流變液的應(yīng)用方向和前景，以及研究現(xiàn)狀和未來發(fā)展方向。

Abstract:

Electrorheological(ER) fluid is an electrical response intelligent material composed of micro/nano dielectric particles dispersed in insulating oil. In the past 70 years since the discovery of ER fluids, a great variety of ER fluids have emerged, but its application in practical industries have been restricted due to problems in mechanical properties, sedimentation properties, redispersibility, zero field viscosity and current density. The emergence of giant electrorheological (GER) fluids has promoted the development of ER fluids to a certain extent, but there are still some problems to be solved in realizing real industrialization. In this paper, recent research results are introduced from three aspects: dispersed phase, continuous phase and additive.The four types of representative particles appearing recently are highlighted. The application direction and prospect, as well as the research status and future development direction of ER fluid are briefly summarized.
