▎ 摘　　要

NOVELTY - The method involves injecting a portion of a graphene oxide slurry into a groove filled with an array grid (100). Graphene oxide slurry is frozen without fluidity. The array grid is taken out from the groove. First graphene oxide is obtained. Another portion of graphene oxide slurry is injected to a gap formed on an upper surface of first graphene oxide after taking out the array grid. Graphene oxide slurry is frozen until the graphene oxide slurry has no fluidity. Graphene oxide slurry is dried to obtain second graphene oxide. Second graphene oxide is carbonized and graphitized to obtain directionally arranged graphene heat conducting foam. USE - Method for manufacturing a graphene heat-conducting foam cotton. ADVANTAGE - The method enables realizing operation in simple manner with high controllability, in-plane heat conducting coefficient and longitudinal heat conductivity coefficient. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (a) a graphene heat-conducting film; (b) an electronic product. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an array grid. Array grid (100) Micro through hole (101) Bracket (102) Slot (200)
