Graphene Modification and Functionalization

Chemical functionalization of graphene enables the material to be processed by solvent assisted techniques, such as layer by layer assembly, spin coating and filtration. Hexagonal boron nitride is electrical insulating, combined with graphene and other 2D materials to make heterostructure devices. The two dimensional graphene sheet structures for field emission of electrons due to the carrier mobility and electron mass. The filed emitter by using multi layered graphene nanostructure, the graphitic structure of pristine graphene and carbon nanotube is the driving force of their interaction. The combination of graphene with carbon nanotubes to produced hybrids increased electrical conductivity, mechanical properties and high surface area.
