静电纺丝技术制备的纳米纤维,具有高比表面积、大孔隙率和三维互通孔道,被认为是一种前景很好的过滤分离介质。本文对电纺丝在过滤中的应用做了综述,简要介绍了电纺丝应用于过滤的国内外发展及现状,特别是产业情况。目前,电纺丝过滤介质研究和应用主要集中在空气、液体、亲和膜及功能过滤膜等几个方面。
Nanofibrous membranes prepared by electrospinning have great potential for filtration and adsorptionbased separations due to high specific surface area, good interconnectivity of pores and high porosity. Reviewed .the development and the current state of electrospinning in filtration field, especially in industrial department. The practical use in air filter, water filtration, affinity membranes, functional membranes and etc. were addressed.
