TL;DR: In this paper, a dual-level packaging technology was used to obtain phase change materials (PCMs) which possess high thermal conductivity and excellent mechanical property, such as high compressive strength and high shape stability.

TL;DR: In this article, a high thermal conductivity shape-stabilized phase change composite material which comprises the following components: 6.7-54.0wt of expanded graphite, 5.3-38.6wt of a porous carbon material and 28.4-81.9wt of an organic phase change substance.

TL;DR: In this article, a graphene-based composite heat conduction membrane and a preparation method for its preparation is described. And the method comprises the steps of loading carbon nanotubes on a carbon fiber substrate, then depositing graphene oxide by means of suction filtration, coating and other modes to obtain a membrane, and then conducting a thermal reduction on the membrane under the protection of inert or reducing gas so as to obtain the graphene heat-conduction membrane.

TL;DR: In this paper, a method for preparing expanded graphite under low temperature decompression conditions comprises the steps of adopting perchloric acid, sulfuric acid and nitric acid to perform acidating intercalation processing, washing and drying on natural flake graphite to obtain expansible graphite, and expanding the expansiblegraphite under the low temperature decomposition conditions.

TL;DR: In this article, a high-stability composite phase-change material is prepared from, by mass, 60-94% of inorganic salt hydrate, 1-3wt.% of a nucleating agent and 5-37wt.%.
