Abstract :This study was aimed to obtain conductive cotton fabric surfaces by chemical oxidative polymerization of pyrrole monomer. For this purpose, iron insert ignore into journalissuearticles values(III); chloride was used as oxidant, and an aliphatic polyether with acidic groups was used as anionic surfactant respectively. Polypyrrole formation on cotton fabric surface was proved by Fourier transform infrared insert ignore into journalissuearticles values(FTIR); and scanning electron microscopy insert ignore into journalissuearticles values(SEM); analysis. The obtained polypyrrole coated cotton fabric samples have been evaluated in terms of electromagnetic shielding effectiveness insert ignore into journalissuearticles values(EMSE); and electrical conductivity. Results showed that polypyrrole coated cotton fabrics have showed about 25 dB EMSE value in 0-3 GHz frequency range.
