NOVELTY - Preparation of graphene nano mesh (GNM) involves using a patterned substrate to imprint a substrate/graphene, and penetrating the convex pattern of the patterned substrate through graphene. USE - Preparation of graphene nano mesh. ADVANTAGE - The method rapidly provides large-area, uniform, low-cost, high-porosity and low-defect graphene nano mesh in various patterns and sizes, and is suitable for preparation of other two-dimensional materials other than graphene such as molybdenum disulfide and boron nitride.
