Nanoscale Approaches for Inhibiting Corrosion: Green Advanced Coatings for Application on Steel Structures and Bridges
Project Information
Project ID:
FHWA-PROJ-09-0059
Project Abstract:
The object of this research 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 anticorrosive 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 lifecycle costs.
Goals
The objective of this research is to leverage the unique advantage of inhibiting corrosion at the nanoscale.
