▎ 摘  要

NOVELTY - Preparing graphene-nanocellulose conductive paper involves mixing graphene oxide and nanocellulose in a water system, so that the total mass concentration of graphene oxide and nanocellulose in water is 0.5-2 wt.%. The pH is adjusted to 3-10, and the reaction is performed under hydrothermal conditions. The reaction product is then dispersed, suction filtered, and dried. USE - Method for preparing graphene-nanocellulose conductive paper used in electromagnetic shielding materials or antistatic materials (claimed). ADVANTAGE - The method enables to prepare graphene-nanocellulose conductive paper has high efficiency, excellent mechanical property, high conductivity and low resistance, in simple, cost-effective and eco-friendly manner.
