Abstract

Space charge distributions and behaviors of polystyrene/polyaniline conducting blends were investigated using a pulsed electroacoustic(PEA) method. It was found that positive charges were accumulated near the cathode with increasing polyaniline content in polystyrene/polyaniline when electric field was applied. Breakdown phenomena was investigated by breakdown test and it was observed that dielectric strength was diminished as polyaniline content was increased. By Scanning Electron Microscopy, corss-sectional views of polystyrene/polyaniline conducting blends were observed that the particles of polyaniline were well distributed in polystyrene.
