Sustainable and Versatile Functionalization of Graphene Layers

, , , ,

Keywords: , ,

Graphene layers were functionalized by using a sustainable, versatile, easily scalable method. Functionalizing agents were prepared through the reaction of a dicarbonyl compound with a variety of primary amines and were mixed and heated in air with a high surface area graphite. Functionalization occurred with high/very high yield, without producing wastes, thanks to a domino reaction which leads to the formation of covalent bonds in peripheral positions. The structure of the graphitic substrate remained substantially unaltered. The solubility parameter of the graphene layers was modified in a broad range of values and this allowed to develop many different applications: for inks and varnishes, rubber composites, bionanocomposites. The technology, named NanoCarbon Up is based on international granted patents.
