Since the carbon nanotubes (CNTs) was first discovered in 1991, it has been of great interest in chemistry physics and materials science rapidly, and has a lot of potential applications in many fields, especially applying in preparation of new mixed matrix membranes (MMM), due to its peculiar mechanical, electronic, chemical properties. The constraints of separation performance of traditional membrane would be conquered by CNTs because of its unique one-dimensional and superhydrophobic tubal structure. Howe...
