US 6,664,355 B2 · Process for synthesizing conductive polymers by gas-phase polymerization and product thereof

Abstract

Disclosed are a process for synthesizing conductive polymers by gas polymerization and product thereof. The process for synthesizing conductive polymers includes the steps of coating oxidant on a substrate surface in the unit of several microns and drying in a dryer, contacting monomers of a gas phase to cause a polymerization to the surface on the substrate, and cleaning the substrate for removing the non-reacted monomers and the oxidant after the polymerization. The present invention reduces the manufacturing process to 2˜3 steps by using the gas polymerization, thereby decreasing the manufacturing cost to two third or more compared with conventional methods. Moreover, the present invention has an excellent thin film property and can freely adjust the electric conductivity.
