Abstract: Carbon nanotubes (CNTs) possess intrinsically 1-dimenstional pore structure and can improve the transfer rate of liquid, which render them ideal separation membrane materials for desalination. To enhance membrane desalination performance via incorporating CNTs into polymeric membrane′s matrix has become a subject in membrane academia. This article reviews recent scientific and technological advances in the development of membrane separation based on carbon nanotubes. The structure and properties of carbon nanotubes are introduced, while the unique properties of carbon nanotubes with respect to membranes separation are described. In particular, this review focuses on the current applications of carbon nanotubes in the field of reverse osmosis, forward osmosis and membranes distillation. Finally, the challenges and opportunities of carbon nanotubes in membrane filed are analyzed and the application potential of carbon nanotubes in membrane separation is presented.
