Investigation of Polypyrrole Coated Cotton Fabrics as Electromagnetic Shielding Material

Öz This study was aimed to obtain conductive cotton fabric surfaces by chemical oxidative polymerization of pyrrole monomer. For this purpose, iron (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 (FTIR) and scanning electron microscopy (SEM) analysis. The obtained polypyrrole coated cotton fabric samples have been evaluated in terms of electromagnetic shielding effectiveness (EMSE) and electrical conductivity. Results showed that polypyrrole coated cotton fabrics have showed about 25 dB EMSE value in 0-3 GHz frequency range.
