Title: Study of Polypyrrole-coated electrospun polystyrene fibres by electrochemical oxidization
Polypyrrole (Ppy) was synthesized via a chemical oxidization method with FeCl3.6H2O (FCHH) on electrospun polystyrene fibres ESPSF. The spinning process was achieved by means of Electrospinning for three solutions of polystyrene PS including 3, 5 and 9 % wt/v of FCHH in dimethyl formamide (DMF). The fibres diameters were monitored by scanning electron microscope SEM before and after coating and it was found that best results were achieved at low concentration of FCHH. Coating with Ppy has been performed in four exposure periods (90, 150, 200, 270 min) in a temperature was at 22C and the results show a direct relation between the mean diameter of fibres with quality of coating. The technique suggests a potential route towards the production of conducting fibre with micro/nanoscale dimensions
