Abstract

Cathodic emission of H2SO4 doped polyaniline (PAni) under low vacuum was observed between 100 V to 2500 V. Compared to the cathodic emission of unheated tungsten filament, the doped PAni showed low current levels than that of tungsten at voltages below 700 V and higher current levels above 700 V. The ability of doped PAni to emit electrons may be attributed to the ability of doped PAni to assume a metallic state where electron transport is possible.
