At present, many preparation methods of Graphene have been developed, such as micromechanical stripping method, epitaxial growth method, chemical vapor deposition method, liquid phase stripping method and redox method. However, the above methods have their own shortcomings more or less, and their efficiency is generally low, and some methods can also destroy the quantum structure of Graphene, greatly affecting the electrical and thermal properties of Graphene. Therefore, the efficient, simple and large-scale preparation of Graphene has become a major difficulty in the relevant fields.
