Abstract
The use of conductive polymers with excellent electrochemical properties and environmental friendliness is becoming increasingly important in the field of metal corrosion inhibition. To this end, a polypyrrole anticorrosive coating was synthesized on the surface of structural steel Q235 via potentiostatic deposition. By altering the deposition potential value in a stirred ice bath, the best deposition performance was achieved. It was found that potentiostatic deposition could yield effective anticorrosive coatings over a wide voltage range. The electrochemically deposited films were all Ppy films with C2O42-. This proposed coating has extended the lifespan of metal materials in civil engineering applications.
