▎ 摘　　要

NOVELTY - Preparing nano cellulose comprises adding graphene-like material, which is 10 wt.% of cellulose in aqueous cellulose solution during the grinding process to obtain nano-cellulose aqueous solution, where the graphene-like material is graphene or its derivatives, oxidized graphene or its derivatives, biomass, or graphene or its derivatives, preferably graphene oxide/graphene biomass. USE - The method is useful for preparing nano cellulose (claimed). ADVANTAGE - The method: solves the problems of the existing method with high-energy consumption, environmental pollution and easy agglomeration problem of nano fibers. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the nano cellulose prepared by the above method.
