Nanoscale Approaches for Inhibiting Corrosion: Green Advanced Coatings for Application on Steel Structures and Bridges
The object of this project is to develop novel, nanotechnology-based green coatings for corrosion protection of new and existing steel highway infrastructure. Two coating systems will be investigated and compared to traditional steel anti-corrosive coatings. The two proposed coatings will use conductive polymer nanoparticles to provide electrochemical corrosion inhibition, carbon-black additives to improve the scratch resistance and toughness of these coatings, and metallic nanoparticles to improve the dispersion of the additives. The proposed new coatings will be compared to a traditional zinc-enhanced, epoxy-based coating for both mechanical strength and corrosion protection. The advantage of the nanotechnology-based coatings lies in their expected ability, with a very low concentration of additives, to provide significant corrosion protection while improving adhesion strength and scratch resistance. This could lead to significant savings in their life-cycle costs.
