Hybrid Nanoparticle-based Anti-corrosion Coatings (RFT-601)
Invention Summary
Polymeric coatings have long been used for corrosion control of metallic structures in civil, mechanical, and aerospace engineering. Recent developments in polymeric coatings include nanoparticle-based systems that claim improved mechanical and corrosion protection properties. However, fabrication of such systems is often time-consuming, utilizes an extensive amount of solvents, and has high energy consumption, making the overall process expensive. Researchers at North Dakota State University have developed novel, hybridized, nanoparticle-based coatings to overcome these limitations. These high-performance, curable coatings comprise a basal layer of modified epoxy, reinforced with hybrid nanofillers and an additional top layer of amphiphobic nanoparticles. The basal layer, by itself, prevents fouling and corrosion of different substrates. The top layer may be brushed or dusted onto the basal coating to impart additional properties such as anti-icing, anti-wetting, and self-cleaning. The primary benefit of these new hybrid fillers is that they retain the essential properties of the polymer while improving performance. Being tested on various substrates, this technology has applications in a myriad of fields..
