In this paper polyester fabrics were pretreated with alkaline solution to improve the ability for the fabric surface to bond with polypyrrole (PPy) coating layer. In situ chemical oxidative polymerization of pyrrole monomer was performed on alkali treated polyester fabrics. Then the fabrics were characterized by FTIR and XRD analysis. The tensile properties of the yarns in both warp and weft directions were measured after alkali treatment and PPy coating processes. The abrasion resistance test was performed on PPy coated fabrics with and without alkali treatment. The surface electrical resistivity of PPy coated fabrics were searched. The electromagnetic shielding effectiveness (EMSE) properties of fabrics in terms of reflection, absorption and transmission behaviors were also investigated. A significant EMSE value increase (about 27%) was obtained with alkali treatment.

The effects of pyrrole, anthraquinone-2-sulphonic acid (AQSA) and iron(III) chloride (FeCl3) concentrations, reaction time and temperature on the electrical conductivity of polypyrrole (PPy)—coated poly(ethylene terephthalate) (PET) fabrics were investigated. With an increase in both the AQSA and FeCl3 concentrations, resistivity decreased to a point beyond which higher concentrations led to increased surface resistivity. Erosion of the polymer coating, in dynamic synthesis from continual abrasion, manifested as an exponential increase in the resistance of the coated textile substrate. This was not encountered in static synthesis conditions. Temperature affected the degree of surface and bulk polymerisation. The effect of polymerisation temperature on conductivity was negligible. Conductive polymer coating on textiles through chemical polymerisation enabled a smooth coherent film to encase individual fibres, which did not affect the tactile properties of the host substrate. The optimum FeCl3/pyrrole and AQSA FeCl3/pyrrole molar ratios were found to be 2.22 and 0.40 respectively. Copyright © 2003 Society of Chemical Industry
The sensitivity and stability are main factors to hold back the applications of Polypyrrole coated fabrics. In this paper we have prepared and characterisation study of two different types of fabric substrates coated by conjugated polymer of conductive polypyrrole in novel and simple techniques of chemical oxidative polymerisation of Pyrrole monomer. The prepared uniformly coated textile fabric substrates were characterised by Fourier transform infrared (FTIR) spectroscopy, Structural analysis of X-ray diffraction spectroscopy and surface morphology study of Scanning electron microscopy (SEM).
Characterisation Study of Conjugated Polymer Polypyrrole Coated Cotton Fabric
A method to produce conducting Polypyrrole (PPy) coated cotton textile fabric substrate sample has been obtained from in-situ chemical polymerization. These textile fabrics are suitable for several applications from antistatic films to electromagnetic interference shielding devices. Theproperties of conducting polymer coated fabric were characterised by using FTIR spectroscopy and structural study of X – ray diffraction spectroscopy (XRD) andmorphological characterisation of scanning electron microscopy (SEM). The results confirm polypyrrole coated cotton fabric as a promising material for EMF shielding application in low cost processing method
