▎ 摘 要
NOVELTY - Producing vertically aligned multilayer graphene sheets comprises placing a substrate in an alumina crucible having a fixed amount of oil, where the oil is edible or non-edible oil and the amount of oil is a minimum of 0.15 plus minus 0.05 ml. The crucible is heated at 800 plus minus 50 degrees C, and then cooled the substrate. USE - Method for producing vertically aligned multilayer graphene sheets. ADVANTAGE - The method produces the vertically aligned multilayer graphene sheets in a simple, cost-effective and eco-friendly manner.
