Abstract

The seawater desalination membrane technology is confronted with the bottleneck of being unable to balance permeability and selectivity. Two-dimensional materials represented by graphene and its derivatives, with their unique nanostructures and excellent physical and chemical properties, offer new ideas for the development of next-generation separation membranes. This paper mainly adopts the literature research method to systematically review the research progress of graphene-based membrane materials in the field of seawater desalination, focusing on two major technical routes: nanoporous graphene membranes and layered graphene oxide membranes. It elaborates on their structural design, preparation process and separation mechanism, summarizes key performance indicators such as water flux (e.g., 22.39 L/m2·h·bar for GO-CD membranes) and rejection rate (>99%), and analyzes core challenges such as swelling, fouling and large-scale production in the transition from laboratory research to practical application. Finally, this paper compares and prospects the industrialization prospects of different technical routes, with the aim of providing references for the future direction of this field.
