Hi Rinki Malik,

For pyrrole polymerization in aqueous solution I don't have an answer. But in organic medium I suggest for you this formulation: 0.1 M pyrrole dissolved in 5 mL acetonitrile as solvent and 0.17 g tetrabutylammonium perchlorate (TBAP) as the supporting salt. You can use galvanosatic method by applying a constant current. In such a way, you can control the thikness of your film: As reported in the literature, a charge density of 500 mC/cm2 corresponds to a film thickness of 1 micron.

There are quite a lot of suitable papers, e.g.:
