Fabrication of Polyacrylonitrile/polypyrrole (PAN/Ppy) composite nanofibres and nanospheres with core-shell structures by electrospinning

One simple method was introduced to prepare core-shell nanostructured conductive Ppy composite. Core Ppy particles were first introduced in the flexible shell solutions and then different core-shell structures can be prepared by electrospinning method. The results showed that: this method is very powerful to form core-shell nanostructures with electroconductive Ppy. (C) 2007 Elsevier B.V. All rights reserved.
