Abstract:
1. A process for fabricating a field emitter electrode, comprising the steps of: applying a conductive polymer onto a substrate; semi-curing the conductive polymer such that the applied conductive polymer forms a non-flowable polymer layer maintainable on the substrate; separating the non-flowable conductive polymer layer from the substrate; depositing carbon nanotubes on the non-flowable conductive polymer layer by electrophoresis: and heat treating the conductive polymer having carbon nanotubes deposited thereon, so as to completely cure it; wherein the step of depositing carbon nanotubes includes connecting the conductive polymer layer to either of two electrodes, impregnating it with a cathode in an electrolyte containing carbon nanotubes dispersed therein and applying a predetermined voltage to both electrodes so as to deposit carbon nanotubes on the conductive polymer layer.
