▎ 摘  要

NOVELTY - Preparing high-strength and high-elasticity graphene aerogel without dropping slag, comprises (a) uniformly mixing graphene oxide solution, dimethylsiloxane oligomer and alkaline catalyst, and obtaining pre-lapped graphene oxide precursor through pre-hydrolysis and pre-tissue reaction, (b) adding foaming agent, reducing agent and dimethylsiloxane crosslinking agent into graphene oxide precursor of pre-lap and stirring and carrying out high temperature reaction to obtain modified graphene wet gel, and (c) performing freezing, freeze-drying and thermal annealing on the modified graphene wet gel successively. USE - Used as high-strength and high-elasticity graphene aerogel without dropping slag. ADVANTAGE - The graphene aerogel without dropping slag has high strength and high elasticity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for high-strength and high-elasticity graphene aerogel without dropping slag.
