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.
