NOVELTY - Preparation of cellulose nanocrystal/graphene/polyvinyl alcohol aerogel involves preparing cellulose nanocrystals, preparing cellulose nanocrystal/graphene mixed solution, preparing cellulose nanocrystal/graphene/polyvinyl alcohol ternary composite solution, carrying out inorganic salt induction, replacing with alcohol solution and freeze-drying. USE - Preparation of cellulose nanocrystal/graphene/polyvinyl alcohol aerogel. ADVANTAGE - The method enables simple, economical and environmentally-friendly preparation of cellulose nanocrystal/graphene/polyvinyl alcohol aerogel with large specific surface area, small pore size, low density, and improved adsorption performance, mechanical properties, biocompatibility and degradability.
