A conductive textile was successfully prepared by covalently grafting polyaniline (PANI) onto a cotton fabric substrate through a three-step approach, including γ-ray irradiation-induced grafting polymerization, functional modification and in-situ redox polymerization. The results of Fourier transform infrared (FT-IR) and X-ray photoelectron spectroscopy (XPS) demonstrated that PANI was covalently grafted onto cotton fabric successfully. The images of scanning electron microscopy (SEM) showed that the surface of PANI grafted cotton fibers were covered with PANI layer, and contact angle (CA) testing indicated the cotton fabric had been transformed from hydrophilicity to hydrophobicity after grafting PANI. When the degree of grafting PANI up to 10.2%, the surface resistance of the resultant fabric can be decreased to 108 Ω/? of level, which means it possess good anti-static property.Cited
