Polypyrrole Films Deposited on Carbon-Steel CS-1018 and Its Interaction with Mexican Crude Oil
Abstrak
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: Cyclic Voltammetry (CV) and Chronoamperometry (CA). The characteristics of film electrosynthesized on the carbon-steel substrate (CS-1018) using KNO3 as supporting electrolyte was studied. The results concluded that under experimental conditions used is possible make a PPy film with adequate characteristics. Important factors were the grip and electrochemical stability of the formed film on steel, which depends on the electrosynthesis technique and in some cases favored by a pretreatment with a 10% HNO3 solution applied to the steel prior to electropolymerization. The results showed that the polypyrrole deposited with pretreatment completely covered the steel surface and showed better stability and grip.
