In this paper, we study the morphological, chemical and electrochemical characteristics of conductive fabrics obtained by weaving conductive yarns of polyester chemically coated with PPy (polypyrrole)/PW12O3-40. The weaving process allows us to obtain conductive fabrics with higher dimensions than those traditionally obtained by in-situ chemical oxidation methods. Untwisted yarns and satin fabrics produced the most satisfactory results. The yarns of PES - PPy/PW12O3-40 as well as the fabric obtained after weaving, were chemically characterized by means of Fourier transform infrared spectroscopy with attenuated total reflection and energy dispersive X-ray. Scanning electron microscopy was employed to observe the morphology of the coating as well as the formation of defects during the weaving process. Electrochemical impedance spectroscopy was employed to measure the conductivity of the fabrics and the conductive nature by means of the phase angle. The process was satisfactory since the coating of polypyrrole was not excessively damaged by the weaving process.
