    Abstract

    We synthesized polypyrrole (PPy) and metal (AgPd) compounds coated on woven polyethylene teraphthalate (PET) and nonwoven polyester (PE) fabrics. PPy coated on PET or PE fabrics was chemically polymerized by using naphthalene sulfonic acid (NSA) as a dopant and electrochemically synthesized by using anthraquinon-2-sulfonic acid (AQSA) as a dopant. Temperature dependences of dc conductivity [δdc(T)] of PPy-NSA/fabric and PPy-AQSA/fabric complexes are compared. The electromagnetic interference (EMI) shielding efficiency (SE) of PPy/fabric complexes is in the range of 20 ∼ 80 dB depending on the thickness and conductivity.
