Abstract：Background: Graphene is a very promising new carbon material developed recently. It has excellent chemical and physical properties, and plays a broad role in the fields of chemistry, physics, electronic devices, power and materials.Research status: The preparation methods of graphene are divided into three categories: one is the top-down synthesis method; the second is the bottom-up synthesis method; the third is other synthesis methods . Top-down synthesis methods include: mechanical stripping method, redox method, liquid or gas phase direct stripping method, cutting carbon tube method, etc.; bottom-up synthesis methods include chemical vapor deposition method, organic synthesis method, and utilization Small carbon compounds produce single-layer or multi-layer graphene. Other synthesis methods such as SiC epitaxial growth, doping method, etc.Research purposes: By comparing the differences between different research methods and the quality of graphene products, the advantages and disadvantages of various methods and their application prospects are obtained.
