Abstract

Electro spinning is an efficient technique for the fabrication of polymer nano-fibres. The charges inside the polymer jet tend to repel each other so as to stretch and reduce the diameter of the polymer fibres. By rotating the collector at a fast angular speed, nano- fibres with specific orientation can be obtained. In this study, nano- fibres of Polyethylene oxide (PEO) with carbon black were prepared by electro spinning. PEO was dissolved in a mixture of water and ethanol. PEO is known as an electrolytic polymer. By blending with carbon black powders, its electrical properties along the fibre direction were improved. The fibre morphology and characteristics were studied by SEM and polarized FTIR.
