▎ 摘　　要

NOVELTY - Preparing electrical sensing fibers by wet spinning comprises (i) acidizing the carbon nanotubes to obtain acidified carbon nanotubes, (ii) providing conductive polymer powder, (iii) dissolving the polyurethane in the solvent to obtain polyurethane solution, (iv) adding conductive polymer powder, graphene and acidified carbon nanotubes to the polyurethane solution, stirring and defoaming to obtain spinning stock solution, and (v) wet spinning the spinning dope to obtain spun fibers, quenching and freeze-drying, performing solvent replacement in water to obtain electrical sensing fibers. USE - The method is useful for preparing electrical sensing fibers by wet spinning, which is useful for medicinal material, clothes, aerospace and shoes. ADVANTAGE - The method: is simple; has convenient operation and good repeatability; does not have electric sensing performance, excellent tensile property, and tensile properties, and can be blended with other fiber.
