Reverse osmosis (RO) desalination technology is one of the most effective approaches for addressing the worldwide water scarcity by producing fresh water from sea water, groundwater and other wastewater sources. However, the traditional method required ehigh nergy consumption, and the process is constrained by several challenges including limited water flux, insufficient salt rejection and an inferior fouling resistance. Highly perm-selective and inexpensive antifouling RO membranes are required in order to reduce the cost and energy input associated with water desalination.

In recent years, with the development of two dimensional (2D) nanomaterials, new strategies for fabrication and modification of thin film nanocomposite (TFN) RO membranes emerged. It was found that atomically thickness 2D layered materials open a new way for tailoring the membrane structure, mechanical strength, surface hydrophilicity, surface charge, charge density and surface roughness in the PA skin layer. | |||||||||||||||
Based on this, the research group of Membrane Science and Technology led by Prof. ZHANG Kaisong from Institute of Urban Environment, Chinese Academy of Sciences, synthesized 2D graphene analogue molybdenum disulfide (MoS2) in high-throughput through ultrasound-assisted solvent exfoliation.
