Graphene nanofl akes and hybrid nanocomposites with gold and silver nanoparticles: optical and thermal properties

Abstract

New technologies for the preparation of graphene nanofl akes (GNF) with noble metal nanoparticles (NPs), specifi cally Au and Ag, as well as hybrid nanocomposites composed of metal microspheres coated with nanostructures [GNF+metal NPs], were considered. The optical properties of metal nanoparticles, their adsorption characteristics with respect to graphene fl akes, and the thermophysical properties of the obtained functional nanomaterials were studied. The obtained data on dynamic optical absorption and thermal conductivity makes it possible to propose new fi elds of application of graphene materials.
