Researchers have demonstrated a superior anticorrosion and antibiofouling performance of polyaniline/graphitic carbon nitride composite coating.
Microorganisms sticking to the coating’s surface might hasten its demise, and corrosive ions are more capable of penetrating the coating-substrate contact, resulting in local corrosion of carbon steel, which is an urgent scientific and engineering problem to be solved. Now, bifunctional anticorrosion and antibiofouling coatings were prepared using polyaniline (PANI) and graphitic carbon nitride (CN) incorporated with epoxy (EP) resins.
Outstanding corrosion resistance
The electrochemical tests’ results revealed that the optimum PANI@CN-10/EP coating possesses outstanding corrosion resistance. The. In addition, the antibiofouling tests presented that PANI@CN/EP coating had favorable anti-biofouling properties with only a tiny number of algae (Phaeocystis globose and Skeletonema costatum) adhered to the surface.
The study has been published in Progress in Organic Coatings, Volume 179, June 2023.
Event tip
Protective coatings are also in the focus of the EC Conference Protective & Fire-retardant Coatings on October 18 -19 in Berlin, Germany. The latest developments in protective and fire-retardant coatings will be presented to you in one conference.
