Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a preparation method of a graphene-nano gold composite tube. Background technique [0002] Graphene is a two-dimensional allotrope of carbon. Since the research team of the University of Manchester successfully obtained single-layer graphene by micromechanical exfoliation in 2004, graphene has attracted extensive attention from researchers from all over the world. Although other allotropes of carbon such as carbon nanotubes, fullerenes, etc. are composed of sp2 hybridized carbon atoms similar to graphene, in terms of mobility, room temperature Hall effect, Dirac electronic structure, light transmittance, None of these allotropes can match graphene in properties such as mechanical strength and thermal conductivity. Because of these attractive properties, graphene has broad application prospects in many fields such as microelectronics, transparent electrode...
