▎ 摘  要

NOVELTY - Preparing (M1) nitrogen-doped graphene, comprises mixing at least one solid-state nitrogen containing precursor with a graphene to form a mixture, and sintering the mixture under a reducing atmosphere to obtain the nitrogen-doped graphene. USE - The method is useful for preparing nitrogen-doped graphene that is useful for producing a composite heat dispatching plate (all claimed) comprising composite heat dispatching materials e.g. nitrogen-graphene with copper foil, nitrogen-graphene with aluminum substrate or nitrogen-graphene with other relevant metal substrates that is suitable for continuous industrial productions. ADVANTAGE - The method: provides the nitrogen-doped graphene having bonding configurations of pyridinic nitrogen (398.1-399.3 eV) and graphitic nitrogen (401.1-402.7 eV), thus reducing structural defects of graphene lattices and exhibiting improved crystallinity and thermal conductivity; and can be performed under normal pressure using commercially available solid-state nitrogen sources without requiring the need of polluting solvents, hence simple, safe (eco-friendly), effective, stable and cost effective. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing (M2) a composite heat dispatching plate (100), comprising mixing the nitrogen-doped graphene with a polymer bonding agent to form a mixture slurry, coating the mixture slurry onto at least one surface of a metal substrate to form a composite material, drying the composite material, and obtaining the composite heat dispatching plate with a coating of nitrogen-doped graphene. DESCRIPTION OF DRAWING(S) - The figure shows a schematic illustration of the structure of a composite heat dispatching plate.
