Research progress on preparation methods and applications of graphene
This article reviews the preparation methods and application of graphene.Graphene can be prepared by exfoliation,chemical vapor deposition,and silicon carbide epitaxial growth.Graphene can be used to prepare transparent conductive electrodes.Large domain graphene films can be prepared via low-pressure chemical vapor deposition with copper oxide foil as the substrate.Adding other components to functional graphene can prepare conductive adhesives with excellent conductivity and thermal conductivity.High conductivity and high thermal conductivity graphene films can be obtained by crosslinking aromatic amine molecules with graphene oxide nanosheets and reducing residual oxygen-containing functional groups at high temperatures,which can be used to prepare directional flexible thermal conductive materials.Nano graphene oxide,azodiisobutymidine hydrochloride,and N-methylpropenylphthalamine can be added to low cross-linked sodium polyacrylate to prepare phase change energy storage materials.
