METHOD FOR PREPARING GRAPHENE PAPER

摘要

Provided is a method for preparing graphene paper, comprising the followings steps: placing a clean substrate into a reaction chamber, then introducing protective gas into the reaction chamber to purge out air in the reaction chamber; heating the substrate at a temperature of 800 to 1100° C.; continuously introducing carbonaceous material into the reaction chamber for 100 to 300 min, stopping the introduction of carbonaceous material into the reaction chamber, and at the same time stopping heating of the substrate, then cooling the substrate at a rate of 5 to 30° C./min, finally, stopping the introduction of the protective gas, thereby obtaining graphene paper on the surface of said substrate.

1. A method of preparing graphene paper, wherein said method comprises the steps of:
S1: Placing a clean substrate into a reaction chamber, followed by introducing therein a protective gas, thereby purging out air in the reaction chamber; S2: Heating said substrate at a temperature of 800 to 1100° C.; S3: Keep introducing a carbonaceous material into said reaction chamber for 100 to 300 min; S4: Stopping the introduction of carbonaceous material into the reaction chamber while stopping heating of said substrate, followed by cooling said substrate at a rate of 5 to 30° C./min; finally, stopping the introduction of said protective gas, thereby obtaining graphene paper on the surface of said substrate.
