Polymer Composites



Polymers possess an assortment of commercial and industrial applications ranging from the foam found in cushioned furniture to the coatings that protect sensitive electronics on military aircraft. The main focus of the Johnson Materials Research Group is modifying polymer systems to achieve enhanced material properties for specialty applications. Recently, polyurethane adhesives, coatings, and foams have been synthesized by the Johnson Materials Research Group from the natural precursor, coal. 



Impressively, the resulting coal derived polyurethanes exhibit increased resistance to thermal degradation and greater yield strength than most commercially available polymers. Through the incorporation of advanced materials such as graphene oxide, oxidized coal char, and carbon nanotubes (also synthesized from coal), mechanical properties of polymer systems are augmented even further and new electrical properties emerge.
