▎ 摘　　要

NOVELTY - Producing heat dissipation material, comprises (a) preparing a porous carbon material by calcining the carbon material, (b) preparing an alkylated ceramic filler by reacting a ceramic material with an alkyl alcohol, and (c) filling the pores of the porous carbon material with an alkylated ceramic filler by stirring and ultrasonicating the porous carbon material and the ceramic filler. USE - The heat dissipation material is useful in heat-resistant epoxy composite and heat dissipation expanded graphite (all claimed). ADVANTAGE - The heat dissipation material can improve heat dissipation characteristics and electromagnetic interference (EMI) by forming a continuous heat transfer path by introducing a plate-shaped ceramic filler composite on a carbon-based material base made of continuous porous structure. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: heat dissipation material in which plate-shaped ceramic filler is filled in the pores of the porous carbon material produced by the above method; heat-resistant epoxy composite comprising a heat dissipation material in which a plate-shaped ceramic filler is filled in pores of a porous carbon material produced by the above method, and mixture of epoxy; and producing heat dissipation expanded graphite, comprising (i) preparing porous expanded graphite by calcining graphite containing sulfur, (ii) preparing alkylated boron nitride by reacting boron nitride with 1-dodecanol, and (iii) stirring and ultrasonicating the porous expanded graphite and the alkylated boron nitride to fill the pores of the porous expanded graphite with alkylated boron nitride. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for producing heat dissipation material (Drawing includes non-English language text).
