✦ Synopsis

Polyaniline (PAn), a n important conducting polymer, was synthesized chemically. Percentage crystallinity of' PAn on doping with various dopants (viz., hydrochloric acid, formic acid, iodine, methylene blue) has been investigated using wide-angle X-ray diffraction analysis. It is observed that percentage crystallinity (Xc %) for PAn increases after doping, and it is different for different dopants. T h e electrical conductivity measurements of these samples show t h a t there is a n increase in electrical conductivity with a n increase in crystallinity. (
