▎ 摘　　要

NOVELTY - A multi-layer graphene structure with controllable distortion angle is prepared by cutting silicon dioxide/silicon substrate of single layer graphene single crystal into 2 parts; spin coating polymethyl methacrylate (PMMA) film along cutting line; using chemical corrosion liquid for layer etching; adhering target graphene with PMMA layer and transferring to new substrate; and rotating the substrate on micro-operation system, and stacking together. USE - Method for preparing multi-layer graphene structure with controllable distortion angle (claimed). DETAILED DESCRIPTION - Preparing multi-layer graphene structure with controllable distortion angle comprises (A) cutting silicon dioxide/silicon (SiO2/Si) substrate of single layer graphene single crystal into 2 parts; (B) spin coating PMMA film along cutting line; (C) using chemical corrosion liquid for layer etching; (D) adhering target graphene with PMMA layer and transferring to new substrate, washing the PMMA with acetone, and attaching the other part into a glass sheet; (E) rotating the substrate on micro-operation system, and stacking together; (F) using acetone for washing PMMA; and (G) retaining selected distortion double-layer graphite alkene.
