Abstract
The present invention relates to a process for producing carbon foam for heat sinks without the need for conventional oxidation stabilization. There is provided a process comprising:
(1) heating a liquified pitch under non-oxidizing, superatmospheric conditions below about 500° C. sufficient to produce a carbon foam;
(2) coking said carbon foam by heating said carbon foam at a temperature above about 500° C. under non-oxidizing, superatmospheric conditions;
(3) heating the coked carbon foam under conditions sufficient to produce a substantially graphitic carbon foam; and (4) at least partially filling porous regions in the substantially graphitic carbon foam with a phase-change material.
(1) heating a liquified pitch under non-oxidizing, superatmospheric conditions below about 500° C. sufficient to produce a carbon foam;
(2) coking said carbon foam by heating said carbon foam at a temperature above about 500° C. under non-oxidizing, superatmospheric conditions;
(3) heating the coked carbon foam under conditions sufficient to produce a substantially graphitic carbon foam; and (4) at least partially filling porous regions in the substantially graphitic carbon foam with a phase-change material.
