Thumbnail image of graphical abstract

Highly pure membranes of double–walled carbon nanotubes (DWCNTs; see figure) have been prepared by combining a purification process with the competition characteristics of water and ethanol interactions with the surface of CNTs. The resulting ultrathin films consist of a single layer of CNTs and they show an enhanced tensile strength. The method can also easily be expanded to other types of nanotubes.
