▎ 摘  要

NOVELTY - Graphene aerogel material comprises 60-80 pts. wt. graphene oxide, 20-40 pts. wt. poly 4-methyl-1-pentene, 10-20 pts. wt. polytetrafluoroethylene, 5-15 pts. wt. resorcinol-formaldehyde adhesive, 40-60 pts. wt. deionized water, 10-20 pts. wt. polymethyl methacrylate, 10-20 pts. wt. polycarbonate and 2-6 pts. wt. catalyst. USE - Graphene aerogel material. ADVANTAGE - The graphene aerogel material has a high light transmittance, make the appearance more beautiful, and has improved and prolonged service life, and also has low shrinkage of graphene aerogel which makes the graphene aerogel with good size stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a novel graphene aerogel material, which involves: (A) pulverizing the appropriate amount of graphene oxide, pouring it into the metal container after the treatment, and add poly 4-methyl-1-pentene, polytetrafluoroethylene, resorcinol-formaldehyde to the metal container Adhesive and deionized water, after stirring for 30 minutes, make a solution with a concentration of 1-10 milligram per millilitre; (B) heating metal container with the solution inside in a water bath at 60 degrees C warm water, and vibrating with an ultrasonic generator for 2-4 hours to obtain an aqueous solution of graphene oxide; (C) taking out the appropriate amount of polymethyl methacrylate and polycarbonate and mixing at a high temperature of 300 degrees C for 1 hour and taking out and cool to room temperature for use; (D) taking the prepared graphene oxide aqueous solution into the reaction kettle, add the catalyst, stir for 20-30min, then put the mixture of polymethyl methacrylate and polycarbonate into the reaction kettle, and heating at 100-300 degrees C for 2-6 hours to prepare graphene oxide hydrogel; (E) placing the prepared graphene oxide hydrogel in an acetone solution for solvent replacement to obtain graphene ketone gel; and (F) taking out the prepared graphene oxide hydrogel and let it cool naturally at room temperature for 2 hours, and then putting it into a cold storage at (-)5 degrees C to freeze-dry it to obtain high-strength graphene oxide aerogel.
