随着现代经济、工业的发展,许多环境问题出现在了人类面前,对于新型吸附分离材料的需求也变得十分迫切。静电纺丝法是一种简单有效制备连续纳米长丝的技术,有着十分广阔的应用前景。由于静电纺丝法制备的纤维膜具有较大的比表面积、易于调控的微观结构及化学性质,静电纺丝法能够用于制备新型的吸附分离材料。本文对电纺纤维膜的制备与改性,以及电纺纤维膜在空气过滤、油水分离、重金属离子去除等领域的应用进行了介绍,同时对其未来的发展进行了展望。
With the development of modern economy and industry,the environment problems are becoming increasingly serious. So the requirements of the novel adsorption / separation materials have become urgent.Electrospinning( ES) is a facile and effective technique to prepare continuous nanofibers and has a wide application prospect. Because the electrospun nanofibrous mat possesses the features of large surface area,controllable microstructure and chemical property,the ES technology is considered as a potential method to prepare novel adsorption / separation materials. This article has summarized the recent researches on fabricating and modifying the electrospun fibrous mat and illustrated its applications in air filtration,oil-water separation and heavy metal ion adsorption. The research prospects and directions of this rapidly developing field are also briefly proposed.
