Production process and application of electrospun nanofibers

The principle of electrospinning process for nanofiber was described.The electrospinning conditions,such as voltage,flow rate,nozzle-to-collector distance,solvent concentration,were discussed.The technology of coaxial electrospinning process for sheath-core superfine fiber and hollow fiber was introduced,as was the application of electrospun nanofiber in the biomedical field.It was pointed out that the electrospun nanofiber is expected to have wonderful prospects in the biomedical field and the development trend of electrospinning process should be foccused on further realizing low-voltage spinning,developing non-toxic solvents and controlling the release property of coaxial electrospun nanofiber.
