Abstract:

Graphene oxide membranes have ultra-high water flux, controllable interlayer spacing and excellent separation properties. These outstanding characteristics make graphene oxide membranes promising to be a new generation of membrane materials and used for the precise separation of substances in the water environment. At present, researchers have performed numerous studies on graphene oxide membranes and achieved breakthrough results, including the transfer behavior of water in the membrane, the separation mechanism of the membrane and the preparation methods of the membrane, etc. However, there is still a lack of comprehensive understanding of graphene oxide membranes. This review systematically described the structural properties and structure-effect relationships of graphene oxide membrane, and summarized the typical preparation methods. In terms of the challenges faced by graphene oxide membrane in practical application, we focused on the existing modification methods of graphene oxide membrane. The applications of graphene oxide membrane in various water environments were also discussed. Finally, the future development of graphene oxide membrane was summarized and prospected. The aim of this paper is to provide novel ideas for the design and synthesis of high-performance graphene oxide membranes for water purification.
