The metasurfaces is a kind of two-dimensional metamaterials with subwavelength scale periodic artificial structure. It can control the incident electromagnetic wave through the structure design. It has a very wide application prospect in various kinds of devices. Graphene has unique electrical, optical, thermal and mechanical properties. More and more attention has been paid to the graphene metasurfaces. The devices with different functions can be designed flexibly and changing the conductivity of graphene and the external voltage. In this paper, the basic concept of metasurfaces is introduced, the development process of various graphene metasurfaces is briefly described according to the classification of metasurfaces, and the problems to be faced and the development trend in the future are discussed.
