NOVELTY - Preparation of high thermal conducting graphite aerogel-based composite thermal interface material involves (i) adding ascorbic acid to deionized water and stirring to obtain a uniform ascorbic acid solution, (ii) stirring the ascorbic acid solution while adding the graphene oxide aqueous solution to obtain a mixed solution, (iii) transferring the mixed solution to the inner lining of the reactor, feeding into the stainless steel shell after sealing, and reacting in the blast drying box, (iv) transferring the reaction product from the inner lining of the reactor to other containers, and washing repeatedly with deionization and ethanol, (v) freezing the sample, and transferring to a freeze dryer for drying, (vi) placing the sample in a mold, compressing the sample with a certain pressure, and pouring the prepared polymer solution into the mold, (viii) drying the mold with the sample in a vacuum drying oven, and (viii) demolding the dried sample from the mold. USE - Preparation of high thermal conducting graphite aerogel-based composite thermal interface material. ADVANTAGE - The method produces self-supporting graphite aerogel-based composite thermal interface material having high longitudinal thermal conductivity, excellent mechanical properties, can be stored easily, and solves the bottleneck problem of heat dissipation of electronic products.
