【Abstract】 A method is reported to impart excellent electrical conductivity to spandex, based on newly emerging technology of in stiu grafting of conducting polymers onto insulating surfaces of spandex. The effects of the amount of aniline, the amount and type of oxidants, the amount and type of “doping” agents and the reaction time and temperature on the electrical conductivity of yarns were investigated in order to obtain the optimum parameters of fabrication of electrically conducting yarns. It was found that the amount of aniline, the amount of oxidant, the amount of “doping” agent significantly affected the conductivity, and the changes of reaction time and temperature had little effect on the electrical conductivity. In addition, the mechanical properties of the yarn were tested, and it was found that the conductive yarn maintained good mechanical properties. Owing to the excellent elasticity of spandex yarn, a potential candidate was discovered for the construction of future intelligent textiles for various uses.更多还原
