Electronically conducting polymers such as polyaniline (PANI), polythiophene (PTh), polypyrrole (PPy) have become the subject of increased research interest due to a great variety of applications in many fields such as electrochromism, electroluminescence, sensors and energy storage systems etc. Among these conducting polymers special interest has been focused on polypyrrole due to its excellent thermal and environmental stability combined with relatively high level of electrical conductivity. In the present research work considerable effort have been made to modify the structure of polypyrrole by doping it with 3-pyridine sulfuric acid (PSA) and 4-sufobenzene acid potassium salt (SBA) to study its dynamic electrical and mechanical properties. For this the polymer, polypyrrole was synthesized by chemical oxidation polymerization method. In this synthesis, 1M aqueous solution of pyrrole was mixed with aqueous solution of ammonium peroxydisulphate used as an oxidizing agent. Further modified polypyrrole was synthesized by doping it with 3-pyridine sulfuric acid (PSA) and 4-sufobenzene acid potassium salt (SBA). The reaction was stirred for 4 hours with a magnetic stirrer to get products as a precipitated. The resulting products were vacuum filtered and the precipitate was washed with copious amounts of AR grade distilled water to remove impurities. The polymers, polypyrrole doped with 3-pyridine sulfuric acid(PSA),4-sulfobenzene acid potassium salt (SBA) were dried in desiccators over night and again dried in oven at 40 – 450 C.
