Hybrid Nanoparticle-based Anti-corrosion Coatings (RFT-601)

Invention Summary

schematic representation of the super amphibhobic nanoparticle polymer coating schematic representation of the hybrid filler-based composite

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 extensive amount of solvents and have 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 of 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 biggest advantage of these novel hybrid fillers is the retention of the polymer’s fundamental properties with enhanced performance. Being tested on various substrates, this technology has applications in a myriad of fields..
