The paper presents the electrostatic charge dissipative performance of conducting polymer nanocomposite impregnated fabric based on polyaniline (PANI) and zinc oxide nanoparticles (ZnO NPs). Conducting polymer nanocomposites (PANI-ZnO NPs) were synthesized by in situ chemical oxidative polymerization of aniline by using sodium dodecyl sulfate as surfactant and HCl as dopant. Coating of PANI-ZnO nanocomposites on the cotton fabric was carried out during polymerization. The interaction of ZnO NPs with the PANI matrix was determined by Fourier transform infrared spectra (FTIR), TGA, XRD, scanning electron Microscopy (SEM), high resolution transmission electron microscopy (HRTEM) and conductivity measurements. The conductivity of PANI-ZnO NP coated fabric was found to be in the range 10(-3) - 10(-6) S cm(-1) depending on the loading concentration of ZnO NPs in the polymer matrix. TEM and HRTEM images showed that the PANI-ZnO nanocomposites had an average diameter of 25-30 nm and were nicely dispersed in the polymer matrix. Antistatic performance of the nanocomposite impregnated fabric was investigated by static decay meter and John Chubb instrument. The static decay time of the film was in the range 0.5 - 3.4 s on recording the decay time from 5000 V to 500 V. This indicated that the nanocomposite based on PANI-ZnO nanocomposites has great potential to be used as an effective antistatic material.
