Preparation of polyaniline/nylon/spandex composited conductive fabric

The paper introduces raw materials,equipments,and methods for preparation of conductive fabrics,as well as conductivity test methods.In order to prepare a fabric with good electrical conductivity,we have developed a flexible intelligent textile with nylon/spandex velveteen knitted fabric as substrate and polyaniline(PANI) as the conductive material,and polyaniline composite conductive fabrics with good conductivity was prepared by in-situ adsorption polymerization and deposition.Single factor analysis was used to investigate the influence of the concentrations of hydrochloric acid and ammonium persulfate,reaction time,and temperature on in the content of PANI and the warp and weft-wise resistivity of the fabric.The conductivity of the fabric as affected process conditions at different stages was analyzed in combination with their reacting principles,and the preparation process conditions were optimized.
