▎ 摘  要

NOVELTY - Directional heat-conducting and heat-radiating integrated carbon material based on graphene-oriented carbon nano-tube array, obtained by (1) dissolving single-layer graphene oxide powder in water, ultrasonically dispersing for 30 minutes to obtain graphene oxide aqueous solution, filtering by vacuum-assisted self-assembly and placing in vacuum oven at 40℃ overnight, (2) placing graphene oxide film in tube furnace, heat reducting at 800℃ for 30 minutes, and obtaining highly reduced graphene film, (3) dissolving polycarbosilane in xylene, and spin coating 2 ml on surface of reduced graphene oxide film, calcining in tube furnace at 1000℃ for 60 minutes to obtain reduced graphene oxide film with silicon carbide engraved on surface, and (4) dissolving ferrocene in xylene to prepare a catalyst carbon source solution, heating in tube furnace to 860℃, injecting the catalyst carbon source solution by micro injection pump to grow the carbon nanotube array and obtaining final product. USE - Directional heat-conducting and heat-radiating integrated carbon material based on graphene-oriented carbon nano-tube array used in electronic device.
