Nowadays

commerically used fiber filtering materials are woven fabric

knitted fabrics and nonwoven materials. The electrospun nonwoven filtering materials have the high specific surface area

high porosity and high pore permeability compared with the traditional fiber filtering materials. They are more easy to separate small particles and they can be used as filtering materials for high precision and high performance. Thus

they have a wide range of applications. In this paper

the research development of electrospun nanofiber preparation and applications has been reviewed. The emphasis is focus on the electrospun nanofiber used as fiber filtering materials in ions-adsorption

aerols filtration and liquid filtration. At the same time

the application of the electrospun nanofiber in special filtration such as anti-bacterium filtration and high-temperature filtration has been introduced. In the end

the prospect of electrospun nanofiber filtering materials has been proposed.
