Abstract

Aqueous dispersions of poly(acrylic acid) (PAA) or polystyrene sulphonic acid (PSS) doped polyanilines (PANIs) designated as PANI-PAA and PANI-PSS, respectively were prepared by in-situ polymerization of aniline in the presence of above acids (PAA and PSS). These. dispersions were coated over cotton fabrics by dip coating technique so as to impart electrical conductivity making them useful for antistatic and electromagnetic interference (EMI) shielding applications. XRD of these fabrics display the characteristic peaks of polyaniline and cotton substrate, whereas SEM images show the presence of conducting PANI coating over individual fibers as well as in the inter-weave regions. There fabrics show rapid (within 0.2 sec) dissipation of static charges and conform to antistatic criteria of 10%-cutoff decay time of less than 2.0 sec. In addition, moderate EMI shielding response was also observed with effectiveness (SE) value of -5.2 dB and -5.7 dB for four layered shields made up of PANI-PAA and PANI-PSS coated cotton fabrics, respectively.
