Infrastructure Research and Technology Strategic Plan and Roadmap|
|Project Description:||The object of this proposal 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 life-cycle costs.|
