Abstract

S band region of electromagnetic spectra is used in versatile applications as in multimedia and communication. Electromagnetic interference makes several electrical, economic, and biological adverse effects. Flexible electromagnetic interference shield from polyaniline-TiO 2 hybrid coated cotton fabric was developed and shielding efficiency of coated fabric was calculated in S band region using cavity perturbation technique. The polyaniline-TiO 2 hybrid coating was done by one-pot method involving in-situ polymerization. The shielding effectiveness due to reflection, absorption, and multiple reflections were estimated and compared for coated fabrics with different polyaniline: TiO 2 ratios. The hybrid coated cotton fabrics had durable electrical conductivity and strength, with good electromagnetic interference shielding in S band region.
