Electrospinning is recognized as a new processing method to prepare nanofibers by emitting and stretching of polymer solution or melts under the electric field.The electrospun textiles possess many advantages such as small pore size

high surface area

very small and even diameters

and high ratios between lengths to diameter

which endow the electrospun nanofibers a broad application.Presently

the study of electrospinning nanofibers has received much attention around the world.In this paper

the equipments of electrospinning

the basic principles of electrospinning

and the research development of electrospun nanofibers were reviewed.Meanwhile

the applications of the electrospun nanofibers in many fields were introduced.At last

the development directions and foregrounds of the electrospun nanofibers were prospected.
