Characterization of conducting polymer coated synthetic fabrics for heat generation

• Heat generation in fabrics coated with the conductive polymer polypyrrole was investigated. The PET fabrics were coated by chemical synthesis using four different oxidizing agent-dopant combinations. The samples from the four different dopant systems all show an increase in temperature when a fixed voltage is applied to the fabric. The antraquinone-2-sulfonic acid (AQSA) sodium salt doped polypyrrole coating was the most effective in heat generation whereas the sodium Perchlorate dopant system was the least effective. The power density per unit area achieved in polypyrrole coated polyester-Lycra(R) fabric with 0.027 mol/l of AQSA acting as dopant was 430 W/m(2). The power density per unit area achieved for the sodium Perchlorate system, using the same synthesis conditions, was 55 W/m(2).
