A programmable pulsed current source was devised to supply the needed instrumentation in the fabrication of conducting polymers. Current ranging from 0 to 1A with square wave frequencies from 0 to 100 Hz at different duty-cycles could be produced by the constructed device. The influence of applying pulsed current in the electrical and mechanical properties of conducting polymer was studied. With the examination of the 4 samples produced, conductivities of the resulting films were observed to increase with higher frequency pulsed current mechanical properties were also seen to improve.
