摘要

Conductive polymers such as polypyrrole, PPy, are materials capable of conducting electrical current.In this paper two techniques for the electrodeposition of PPy on carbon steel were used: CyclicVoltammetry (CV) and Chronoamperometry (CA). The characteristics of film electrosynthesized onthe carbon-steel substrate (CS-1018) using KNO3 as supporting electrolyte was studied. The resultsconcluded that under experimental conditions used is possible make a PPy film with adequatecharacteristics. Important factors were the grip and electrochemical stability of the formed film onsteel, which depends on the electrosynthesis technique and in some cases favored by a pretreatmentwith a 10% HNO3 solution applied to the steel prior to electropolymerization. The results showed thatthe polypyrrole deposited with pretreatment completely covered the steel surface and showed betterstability and grip.
