▎ 摘　　要

NOVELTY - Graphene casting comprises pouring 0.5-0.7 mu g/mL graphene oxide dispersion in a hydrothermal reactor cup, and adding ammonia or sodium hydroxide to form a mixed solution with a pH value of 5.5-11.6; heating the hydrothermal reactor at 150-350 degrees C for 3-48 hours to obtain a graphene gel; and drying the graphene gel at 20-70 degrees C. USE - Method for graphene casting. ADVANTAGE - The method is simple, and regulates mechanical property of the graphene casting.
