Abstract

Conducting polymer TFT was fabricated with gravure printing technique using a vapor polymerization method. Polyvinyl alcohol (PVA) with excellent film forming characteristics was used as a matrix polymer. After the printing of the oxidant dispersed PVA dissolved in DI water, the vapor polymerization of the pyrrole monomer formed a thin conducting polymer film. The conductivity of the film was dependent on the concentration of the oxidant and the polymerization time. In order to be used for TFT application, the conductivity had to be reduced by controlling the various conditions. The effect of exposure to humidity on TFT signal was studied.
