▎ 摘  要

NOVELTY - Manufacturing nano-cellulose/graphene organic-inorganic composite sheet involves reforming the surface of the nano-cellulose material with an aromatic compound and producing a sheet with a nano-modified cellulose materials. The nano-cellulose/graphene-inorganic composite sheet is finally prepared by coating the prepared sheet with graphene. USE - Method for manufacturing nano-cellulose/graphene organic-inorganic composite sheet which is used in making separation film for lithium ion battery, solar cell, electronic paper, sensor lamp and super capacitor(claimed). ADVANTAGE - The method enables to manufacture nano-cellulose/graphene organic-inorganic composite sheet that has excellent tensile strength, improved mechanical strength, excellent optical property with visible light transmittance greater than or equal to 80% and is eco friendly.
