Abstract For a long time, human beings have been yearning for free regulation of light waves. But it is limited by poor performances of the natural materials. The emergence of two-dimensional(2D) synthetic nanomaterials greatly promotes the developments of light control technologies, which has dramatically improved the ability of human beings to control light. People can realize flexible regulation of the propagation speed or propagation direction of light wave in material, optical response and frequency, polarization state of light wave based on a series of novel photoelectric properties of 2D synthetic nanomaterials. So, 2D nanomaterials enabled light control technologies have become a research hotspot in recent years. In this review, we summarize the various technologies realized by 2D materials and introduce the related applications. We further analyze, compare these technologies. This review is aimed to give a generalized knowledge of 2D nanomaterials-enabled smart light regulation technologies and their current devices applications, and thus inspiring the exploration and development of other kinds of new light regulation devices and various novel applications. The challenges and the prospects of the future, especially the application of artificial intelligence (AI) in research and development of 2D materials, are also given.
