“…The three techniques agree closely, with CNT densities averaging 5.2 × 10 11 , 5.1 × 10 11 , and 6.5 × 10 11 CNT cm −2 for weight gain, X‐ray attenuation, and KCl diffusion, respectively. These density values correspond to a porosity of 4.4%–5.5%, which is greater than those of previously reported CNT membranes fabricated from as‐grown CNT forests or CNT dispersion . Note that a large porosity is desirable to boost breathability.…”

“…Indeed, although fabrication of polymeric membranes having dispersed CNTs as fillers in the polymer matrixes have been reported quite many times, the polymeric membranes with aligned CNTs for practical water treatment process have not been extensively studied. Recently, Kim et al developed a novel in situ bulk polymerization method to prepare vertically aligned polymeric CNTs-based composite membranes [77]. Briefly, a vertically aligned CNTs array was infiltrated with polymer monomer followed by in situ polymerization.…”

Membrane separation technology is widely explored for various applications, such as water desalination and wastewater treatment, which can alleviate the global issue of fresh water scarcity. Specifically, carbon nanotubes (CNTs)-based composite membranes are increasingly of interest due to the combined merits of CNTs and membrane separation, offering enhanced membrane properties. This article first briefly discusses fabrication and growth mechanisms, characterization and functionalization techniques of CNTs, and then reviews the fabrication methods for CNTs-based composite membranes in detail. The applications of CNTs-based composite membranes in water treatment are comprehensively reviewed, including seawater or brine desalination, oil-water separation, removal of heavy metal ions and emerging pollutants as well as membrane separation coupled with assistant techniques. Furthermore, the future direction and perspective for CNTs-based composite membranes are also briefly outlined.

“…Reasonable pore channels, high porosity and proper surface properties may dominantly ingratiate this desire. For this purpose, numerous approaches have been investigated to manipulate carbon nanotubes (CNTs) into macroscopic aligned CNT membranes with extremely large gas or water permeation [1][2][3][4][5]. Molecular dynamics simulations have shown the single-file transport for water along the nanotube axis [6][7][8], and the fast flow velocities are predicted from the almost frictionless interface at the CNT wall [9].…”
