摘　　要：当前,工业制造过程中产生的含有有机污染物和有毒金属离子的工业废水对环境的污染越来越严重。而且金属离子和有机物在水中不能自发降解,这对人类的生命健康构成巨大的威胁。与此同时,针对水体净化和污染物去除的研究也已经取得了丰硕的成果。静电纺丝纳米纤维由于其可调控的纤维直径、高孔隙率以及高比表面积在水净化领域具有独特优势,引起了广泛的研究兴趣。综述了有机-无机杂化静电纺丝纳米纤维膜材料近年来在污染物吸附、抗菌、光催化及超疏水等水净化领域的应用研究进展,阐明了各种有机-无机杂化纳米纤维膜对污水净化的优势和效果等,并对其在未来水净化方面的发展趋势进行了展望。Contamination of water by organic pollutants,bacteria,and toxic metal ions generated from industrial processes is an urgent concern which must be addressed.These organic pollutants and metal ions cannot be digested,naturally.As a result,a great deal of research work in the removal of toxic pollutants from contaminated water has been carried out and some promising results have been achieved.Electrospun nanofibers,especially organic-inorganic hybrid nanofibers,have a unique advantage in water purification due to their adjustable fiber diameter,high porosity,high specific area,and high functionalizability,which raises researchers extensive interests.Here,we review the progress of organic-inorganic hybrid nanofibrous membranes in terms of pollutant adsorption,bacterial removal,and photo-degradation for water purification.The advantages and efficiencies of various organic-inorganic hybrid nanofibrous membranes were demonstrated and elucidated,systematically.Future prospects in the developing trends of such membranes for wastewater treatment have been explored.
