Abstract: One-step oxidation-reduction reaction was adopted to prepare polyaniline/Ag composite conductive fabric. The composite conductive fabric was characterized by surface morphology, chemical composition and thermo stability using SEM, FT-IR, XPS and TGA, respectively. The conductive performance and mechanical properties of the polyaniline/Ag composite conductive fabric were evaluated. The influence of washing times on its conductive properties was also investigated. The results revealed that one-step oxidation-reduction reaction can form polyaniline/Ag composite coating on the surface of polyester fabric. The composite conductive fabric has a higher thermal decomposition temperature and better conductive than polyaniline coated fabric, while it retains the basic mechanical properties of the polyester fabric. The conductivity of composite fabric was still better than that of polyaniline coated fabric, after 50 times washing. This study provides a new method for the development of conductive fabric with low cost and high conductivity.
