Vapor phase polymerization of 3,4‐ethylenedioxythiophene on flexible substrate and its application on heat generation

An oxidative chemical vapor phase polymerization process is applied to coat flexible polyethylene terephthalate (PET) fabrics with a uniform poly(3,4-ethylenedioxythiophene) (PEDOT) film. This vapor phase polymerization method is a solventfree technique, which could yield a low resistance in the PEDOT-coated PET fabric. The resistance as low as 52 Ω square−1 is achieved. The polymerization conditions, such as the concentration of oxidant, reaction time, and temperature, have been systematically investigated. The coated fabric samples exhibit an increase in temperature when subjected to a fixed DC voltage. This result indicates a potential application of these PEDOT-coated fabrics as electric heating materials. Copyright © 2009 John Wiley & Sons, Ltd.
