NOVELTY - Producing aerogel based on composite of graphene and carbon nanotubes involves combining graphite flakes with mixture of concentrated sulfuric and nitric acids, diluting with water, filtering and washing precipitate with water. The precipitate is dried at high-temperature to obtain first intermediate as powder. The first intermediate is added and mixed with sulfuric acid to obtain suspension which is added and mixed with potassium persulfate and phosphoric anhydride. The mixture is cooled, filtered, washed and dried at room temperature to obtain second intermediate as powder. USE - Method for producing aerogel based on composite of graphene and carbon nanotubes (claimed). DETAILED DESCRIPTION - Producing aerogel based on composite of graphene and carbon nanotubes involves combining graphite flakes with mixture of concentrated sulfuric and nitric acids, diluting with water, filtering and washing precipitate with water. The precipitate is dried at high-temperature to obtain first intermediate as powder. The first intermediate is added and mixed with sulfuric acid to obtain suspension which is added and mixed with potassium persulfate and phosphoric anhydride. The mixture is cooled, filtered, washed and dried at room temperature to obtain second intermediate as powder. The second intermediate powder is mixed with concentrated sulfuric acid at reduced temperature, followed by the addition of resulting suspension potassium permanganate. The reaction mixture is stirred, diluted with water, and hydrogen peroxide is added. The colloidal solution is washed with water and solution of hydrochloric acid is added and mixed. The mixture is filtered or centrifuged to obtain colloidal solution of graphene oxide. The colloidal solution of graphene oxide colloidal solution of carbon nanotubes is mixed with organic reducing agent and mixture of these colloidal solutions are mixed to obtain final mixture which is mixed with hybrid airgel based on a composite of graphene and carbon nanotubes. The hybrid hydrogel is lyophilically dried to obtain airrel based on composite of graphene and carbon nanotubes. The product is treated at hightemperature treatment and microwave radiation is applied in a microwave oven. Thcolloidal solutions of graphene oxide and carbon nanotubes are mixed in volume ratio of 12:1. The organic reducing agent is D-glucose which is added and frozen-dried and treated with microwave radiation in microwave oven. The hydrophilization of airgel is performed with dilute mixed solution of nitric acid and hydrogen peroxide.
