▎ 摘  要

NOVELTY - Preparing nano-cellulose/graphene composite flexible film involves preparing nanocellulose uniform dispersion by dispersing nano-cellulose in a solvent to obtain a uniform nano-cellulose dispersion. The graphene is added to solvent, and dispersion is distributed by ultrasound to obtain a uniform dispersion of graphene. The uniform dispersion of nanocellulose and uniform dispersion of graphene are mixed, reaction solution is sonicated and stirred to obtain a uniformly dispersed colloidal solution. After removing solvent and drying, a nano-cellulose/graphene composite flexible film is obtained. USE - Method for preparing nano-cellulose/graphene composite flexible film used as flexible battery substrate or flexible catalytic carrier (claimed) and used in flexible electrons, catalysis, and electrochemistry. ADVANTAGE - The method enables to prepare nano-cellulose/graphene composite flexible film, which has good flexibility and transparency, is uniformly dispersed in a solvent including water, and remains stable for a long time, uses rich source of raw materials, has simple operation process, low cost, environmental protection, and high efficiency and has high purity, uniform composition and good composition structure.
