▎ 摘  要

NOVELTY - Highly flexible graphene-type thermal conductive structure prepared based on a hydrothermal method, comprises multiple layers of monolayer graphene stacked in a zigzag form, and a graphene aqueous solution is poured between the monolayer graphenes, and the graphene aqueous solution is heated in a water bath to form dense filling, and the concrete processing steps are as follows (1) preparing multiple single-layer graphenes and bending them, (2) stacking the single-layer graphene that has been bent, (3) inserting the laminated graphene into the filling mold, and injecting the mixed graphene solution into the filling mold with a syringe, and filling the gap of the single-layer graphene, (4) placing the filling mold in a water bath heating kettle, (5) fully heating under the environment of 120-130℃, forming solid plate, and taking out, and cooling, and (6) placing the colloidal sheet into a high temperature environment for heating and curing, and curing to obt6ain final product. USE - Used as highly flexible graphene-type thermal conductive structure prepared based on hydrothermal method. ADVANTAGE - The structure adopts single-layer graphene material with high heat-conducting ability. The bonding of single layer graphene through the structure of the gas-type gel, but in the curing process, does not pass through the ice bath step, to prevent the ice crystal to generate gas-gas gel gap structure, resulting in loss of heat conducting ability. At the same time, the single layer structure of solidified graphene material for protecting single layer graphite not damaged, so as to give a certain structural toughness of the whole flexible graphene flexible, heat conducting structure to prevent it from damage in the process of using. The method reduces the radiating ability of the graphene, but greatly enhances the heat conducting efficiency. The volume is less than half of the heat pipe, and the structure strength and processing cost is lower. DESCRIPTION OF DRAWING(S) - The drawing shows an ideal condition for the graphene of the underlying layer.
