Abstract

Cotton fabrics have been treated with polypyrrole by oxidative <i>in situ</i> chemical polymerization to make them electrically conductive. Ammonium peroxidisulphate is used as an oxidizing agent to overcome corrosion problem caused by ferric chloride. The effect of polymerization duration, monomer concentration, and dopant addition has been studied with respect to conductivity and tensile strength of fabric. Coating of polypyrrole layer is evaluated in terms of electrical conductivity measurement. The conductive fabrics are characterized by HZATR- FTIR characterization and scanning electron microscopic analysis. Addition of dopant is found to improve conductivity of the fabric.
