NOVELTY - Preparing graphene aerogel involves dissolving graphene oxide and crosslinking agent in water to form a uniform solution to obtain a mixture through hydrothermal reaction. The mixture is washed and filtered with an organic solvent to obtain a black solid, and the black solid is soaked in an organic solvent for 0.5-12 hours, and then the black solid is ignited, and the graphene aerogel is obtained when the flame is extinguished. USE - Method for preparing graphene aerogel used in sound insulation, heat insulation, damping, adsorption and electrode materials, supercapacitors (claimed). ADVANTAGE - The method enables to prepare graphene aerogel is simple to operate, has low requirements on reagents and equipment, and does not need to use complex instruments such as freeze dryers or supercritical dryers to facilitate large-scale production.
