Funding from a 2015 PTT Grant will aid North Dakota State University’s Long Jiang in developing new coatings for outdoor metals. His project aims to develop a coating system that is especially tailored toward metallic heritage conservation. The coating possesses a unique combination of properties including strong coating strength and controlled barrier properties, enhanced corrosion resistance and easy removal (when needed). These properties are realized by innovative uses of biobased cellulose nanofiber networks, a non-toxic electroactive polymer and the thermally reversible Diels-Alder reaction, respectively. Eco-friendliness of the new coating is also improved because of the uses of the biobased nanofibers and the non-toxic electroactive polymer. The properties exhibited by the new coating are not currently available on any commercial products.
