Electrospun nanofibers from a new and high-productive needleless apparatus based on sputtering
This paper proposes a new needleless electrospinning apparatus applying the method of splashing polymer solution on to the surface of metal roller. It is mainly composed of three parts -supplying polymer solution system， metal roller spinneret and collector part. The polymer solution provided by the uniformity distribution device is splashed on to the surface of metal roller which is rotating.when a high voltage is applied in addition to the metal roller, many cone-jets can be formed. Multiple electrified jets undergo strong stretching by the electric field and bending instability, solvent evaporates and solidified nanofibers deposit on the collector, as in an ordinary electrospinning process. This machine has a good adaptability for producting kinds of nanofibers. The average diameter 213nm of PLLA nanofibers have been produced,so are the average diameter 174nm PEO nanofibers.The rate of fiber production is as 24-45 times as that of the single needle electrospinning applied widely.
