Endurable conductivity of nylon fibers by interfacial grafting and aniline polymerization

Interfacial grafting was combined with aniline polymerization to modify nylon fibers for high and endurable conductivity. A large amount of acrylic acid grafted to the surfaces of nylon66 fibers. The grafted polyacrylic acid further promoted in situ polymerization of aniline within the interfacial layer of nylon fibers. The electric conductivity of the final nylon fibers reached an unprecedentedly value of 1.1 S/cm. The presence of strong adhesion between polyaniline layer and nylon fibers further significantly promoted the rub resistance and water resistance of conductive fibers. (C) 2018 Elsevier B.V.
