▎ 摘　　要

NOVELTY - Improving elastic modulus of paper by adding graphene oxide involves graphene oxide molecules forming chemical bond and/or hydrogen bond with plant fiber. The adsorption bonding between non-plant fibers and enhance strength of composite paper. The pulp is removed from pulp to prepare slurry. The aqueous solution of graphene oxide is added to acidic or neutral solvent. The graphene oxide is diluted and pH is adjusted. The pulp is added to dilute graphene oxide solution. The mixed solution is dispersed and dried to obtain high elastic modulus graphene composite paper. USE - Method for improving elastic modulus of paper by adding graphene oxide (claimed). ADVANTAGE - The method enables to obtain paper having high elastic modulus.
