Abstract: The velveteen woven knitted by Nylon, Spandex as matrix material, and PANI as the conductive material, using In-situ adsorption polymerization to deposit on the fabric and made a good electrical conductivity of polyaniline composite conductive fabrics. Introduction the raw materials of the conductive fabrics, equipment, preparation methods, test methods, and the related calculations in detailed. Studied the concentration of hydrochloric acid and ammonium persulfate, the reaction time, and the reaction temperature various process conditions on in the content of PANI and the resistivity of warp and weft-wise of fabric. Through graphics comprehensively analyzed the relationship between the content of PANI and the resistivity of warp and weft-wise of fabric. Combination each of the oxidative polymerization reaction condition under took place in the principle, summed up the different stages of the process conditions in the preparation of the conductive fabric that exist effects, and to explore the suitable range of process conditions about the preparation of conductive fabric. In addition, in order to improve its conductivity, to prepare superior PANI composited conductive fabric, and to promote the applications of PANI composited conductive fabric, the prospect about the direction of this research has been made.
