Abstract

A conducting polymer, polypyrrole (PPy) doped with antraquinone sulphonic acid (AQSA), was coated chemically onto polyester (PES) fabrics. PPy was then deposited in sequence on the conducting fabrics (PES covered with PPy/AQSA) by constant-current electrolysis. Electrochemical polymerization (EP) was carried out for different electrolysis times. The weight percent gain, thickness, electrical conductivity and maximum temperature of the PPy-PES increased with the electrolysis time. The structural changes accompanied were examined by SEM and FT-IR. The electrical conductivity ranged from 1.5 to 6.5 S/cm. When a fixed voltage was applied to the PPy-PES, the maximum temperature was increased by more than $90^{\circ}C$. Such conducting PPy-PES fabrics can be used for flexible heating element by 6.0 V DC.
