(57) Abstract: This invention relates to a process for preparation of doped conducting polymer film. More particularly it relates to deposition
of polyaniline films on negatively charged electrode in an electrochemical bath . The present invention provides a process for the preparation
of doped conducting polymer film which comprises coating a substrate with an adhesion promoter film, depositing the conducting metal film
on a substrate, placing the metal coated substrate in an electrochemical cell with three electrode configuration having reference, counter and
working electrode and an electrolyte containing 0.01to 0.5mol of monomer, protonic acid and .001 to 2.0 mole of an initiator, applying a
steady negative potential of -0.3 to -1.1 volts for a period ranging between 30 to 150 min to obtain the desired polyaniline film deposited on
the cathode.
