Abstract：

Carbon nanotubes (CNTs) is a novel allotrope of carbon with a unique tubular structure. In recent years, CNTs has been finding more and more applications in the preparation of functional composite materials due to its unique physical, chemical, and thermal properties. Its applications in separation membranes have also drawn much attention recently. These studies mainly focused on using CNT as an inorganic filler of polymeric membranes, It has been shown that CNTs display an excellent transport ability for gas and liquid molecules when used as membrane filler. In this paper, the recently reported work on CNTs-polymer hybrid membranes was reviewed. Subsequently, the alignment of CNTs in polymeric membrane matrix is introduced in brief. However, so far there is no suitable theory to explain the influence of CNTs on separation membrane structures and properties. Also, good dispersion and ordered alignment of CNTs in polymer matrix is still difficult to realize.
