▎ 摘　　要

NOVELTY - Preparing highly elastic hydrophobic graphene/nanocellulose composite aerogel comprises (1) preparing graphene/nanocellulose composite hydrogel, (2) preparing graphene/nanocellulose composite aerogel, and (3) preparing highly elastic hydrophobic graphene/nanocellulose composite aerogels. USE - The method is useful for preparing highly elastic hydrophobic graphene/nanocellulose composite aerogel. ADVANTAGE - The method: exerts high elastic effect of rubber by high temperature heating and crosslinking; enhances the high elasticity and surface hydrophobic and lipophilic properties of graphene/nanocellulose composite aerogel; and achieves oil-water separation by utilizing the high adsorption properties of the composite aerogel mesh itself.
