Abstract

By aniline (ANI) diffusion and chemically oxidative polymerization, PANI was adherently deposited on PET fibres and Nylon fabrics PANI-PET fibres and PANI-Nylon fab rics doped with HCl have an electric conductivity as high as 0 42 S/cm and 0 45 S/cm respec tively With p-toluenesulfonic acid (p-TSA) and dodecylbenzene sulfonic acid (DBSA) and 5- sulfosalicylic acid (SSA) as dopants, the conductivity and final composites is one or two orders of magnitude lower than that with HCl A washing test was designed to investigate the interfacial ad hesion of PANI on textiles Results showed that the conductivity and interfacial adhesion of composites are improved greatly by preliminary aniline diffusion treatment of textiles Further in vestigations by SEM and WAXS and DSC showed that the improvement in properties of com posite textiles is mainly attributed to the increased interaction of macromolecules at the interface caused by the diffusion of PANI chains in the surface layer of the substrates
