“…The conducting polymer becomes physically adsorbed rather than chemically bonded to the substrate but its adhesion is strong. Various fabrics have been used in the literature as a substrates for the coating with polypyrrole: cotton [7,11,14,20-22, 24,44,45], linen [19], polyamide [17][18][19]33,46], polyester [19,25,46,47], poly(ethylene terephthalate) [10,23,46,48,41], polypropylene [49], silk [26,50], viscose [19,49], or wool [45,48,[51][52][53]. In some cases fabrics were cleaned before the polymerization to remove impurities [3,43].…”

Development of electro‐magnetic shield is an important research area since few decades to protect electronic devices and even human beings from harmful effects of electro‐magnetic rays. Textile based flexible shields are also developed as functionalized materials for this purpose. In this work, needlepunched nonwoven textile based electro‐conductive fabric is prepared by in‐situ chemical polymerization of pyrrole and their effectiveness as electro‐magnetic shield is explored. 33 Box‐Behnken design is used to investigate the influence of manufacturing process parameters of neddlepunched nonwoven fabric such as fabric gsm, punching density and depth of needle penetration on the polypyrrole add‐on, surface resistivity and electro‐magnetic shielding effectiveness. Surface resistivity as low as 18 Ω (with 16.28% polypyrrole add‐on) is obtained for a typical composite fabric. The shielding effectiveness of this fabric is found to be 20.07 dB at 4 GHz frequency. It has been found that the primary mechanism of the shielding is the absorption of electro‐magnetic rays into these composite fabrics rather than reflection from their surface. POLYM.

The surface resistance of polypyrrole (PPy)-coated polyester fabrics was investigated and related to coating thickness, which was controlled by adjusting the reactant concentrations. The thickness of the coating initially increased rapidly followed by a steady increase when the concentration of pyrrole (Py) was larger than a concentration of approximately 0.4 mg/ml. The surface resistance decreased from 10 6 to 10 3 V with increase in pyrrole concentration within 0.2 mg/ml until the concentration reached a value of about 0.4 mg/ml, above which the rate of decrease diminished. The effect of initial treatment with monomer or oxidant prior to polymerisation reaction with regards to thickness and surface resistance was minimal. The immersion time of the textile into the monomer solution prior to polymerisation reaction did not have a significant effect on the abrasion resistance. D
