Abstract
Preparation of conductive cotton fabrics, by polymerization of pyrrole in presence of FeCl 3 as an oxidizing agent and tetraethylammonium p-toluene sulfonat (TEAp-TS) as a doping agent which in turn caused a reduction in the moisture regain of the substrate, resulted in production conductive cotton fabrics in laboratory scale. Factors affecting the proper ties of the fabrics were studied, such as ratio between FeCl 3 and TEAp-TS and pyrrole concentration. Polypyrrole coated cotton fabrics were characterized by scanning electron microscopy (SEM) and Fourier transform-infrared (FT-IR) spectroscopy. Resistivity, weight gain, color strength, tensile strength and elongation of the coated fabric with polypyr rol were monitored according to ASTM procedures. The results had shown that, the conductivity, weight gain, color strength, tensile strength and elongation increase by increasing FeCl 3 , TEAp-TS and pyrrole concentration. This is due to the increase of amount of the conductive polymer on the fabric surface. FeCl 3 (0.25 M/L), TEAp-TS (0.125 M/L), pyrrole (0.3 M/L), temperature (25° C ) and time (4 h) represented the most appropriate formulation for effecting polym erizing of pyrrole and anchoring on cotton fabrics.
