▎ 摘　　要

NOVELTY - High thermal conductivity flexible heat pipe of graphene-coated carbon nanotube aerogel comprises shell, liquid absorbing core, and cooling liquid in order from outside to inside. The liquid absorbing core is carbon nanotube aerogel with regular microporous pipes after foaming, the outer shell is covered with a graphene film with the same specific and high thermal conductivity, and the cooling liquid is ethanol. USE - High thermal conductivity flexible heat pipe of graphene-coated carbon nanotube aerogel. ADVANTAGE - The high thermal conductivity flexible heat pipe has better stability, better corrosion risk than metal-based material under exposure to acid, base, and humidity, and have much higher thermal conductivity than traditional metal material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high thermal conductivity flexible heat pipe of graphene-coated carbon nanotube aerogel, which involves: (a)mixing the solutions of sulfuric acid and hydrogen peroxide to obtain a sulfuric acid/hydrogen peroxide mixed solution;(b) soaking carbon nanotube film in the obtained sulfuric acid/hydrogen peroxide mixed solution, expanding gradually expanded into the three-dimensional aerogel adjusting the pore size and density of the aerogel by controlling the soaking time;(b)washing the aerogel multiple times in deionized water until the pH value reaches 7, drying in an oven to obtain the foamed carbon nanotube aerogel, placing the obtained foamed carbon nanotube aerogel with one side up in a plasma treatment machine;(c)performing hydrophilic treatment on its surface, wrapping graphene film on the outside of the foamed carbon nanotube aerogel through the waterproof adhesive of Plexus MA 300 (RTM:a two-portion methacrylate adhesive);(d) injecting the ethanol solution into the carbon nanotube-graphene flexible heat pipe, performing vacuum sealing:(e)coating the one end of the graphene tube with carbon nanotube aerogel is sealed with a hot melt gun, and the other end is connected to a V-shaped tube;(f)connecting the one end of the V-shaped tube to the vacuum system;(g)starting the vacuum system, pumping to -60 megapascal;(h)connecting the other end of the V-shaped tube into the ethanol working solution by a micro pump with an accuracy of 0.001 mg, and sealing the V-shaped plastic tube with a hot melt gun. DESCRIPTION OF DRAWING(S) - The drawing shows a macroscopic view of a carbon nanotube aerogel with microporous pipes after carbon nanotube film foaming.
