Novel wet electrospinning system for fabrication of spongiform nanofiber 3-dimensional fabric

Electrospinning method is a simple and efficient method to fabricate the nanofiber non-woven mat from a rich variety of functional materials. However, it is difficult to control the 3-dimensional structure of nanofiber fabric via electrospinning method. On that point of view, novel wet electrospinning system was established for the 3-dimensional structure control of nanofiber fabric by combining electrospinning system and wet spinning system. Spongiform Poly (glycolic acid) (PGA) nanofiber 3-dimensional fabric controlling the fiber density was Successfully formed with simplicity and cheapness using novel wet electrospinning system. Comparing with usual PGA nanofiber non-woven mat prepared by conventional electrospinning method, spongiform PGA nanofiber fabric had low apparent density and high porosity. The novel nanofiber fabrication system would be very useful for the structure control of the nanofiber fabric. (c) 2008 Elsevier BY. All rights reserved.
