▎ 摘　　要

NOVELTY - Preparation of graphene paper involves placing a clean substrate into a reaction chamber, introducing protective gas into the reaction chamber to purge out air in reaction chamber, heating the substrate at 800-1100 degrees C, continuously introducing carbonaceous material into the reaction chamber for 100-300 minutes, stopping introduction of carbonaceous material into the reaction chamber, at same time stopping heating the substrate, then cooling the substrate at rate of 5-30 degrees C/minute, and stopping introduction of the protective gas, to obtain graphene paper on surface of substrate. USE - Preparation of graphene paper (claimed).
