“…Up to now, many polymers have been involved to prepare these CNTs-based composite membranes including polyvinylidene fluoride (PVDF), polyethersulfone (PES), polysulfone (PSF), polyvinyl alcohol (PVA), and polyacrylonitrile (PAN) [65,66,67,68,69,70,71,72,73]. Generally, a homogeneous blending solution was prepared by mixing CNTs and polymers in a suitable solvent through stirring or sonication.…”

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.

“…b 0 , n, and e are regression coefficient, number of factors studied and optimized in the experiment, and model random error, respectively. 38 Statistical analysis of the results and the model adequacy evaluation were carried out via analysis of variance (ANOVA). ANOVA includes some statistic factors such as F-value, R 2 , adjusted R 2 and P-value that properly identify the signicance of the main effects, interactions of factors and the produced model adequacy.…”

“…Recently, the research on nanofiltration membranes for removal dyes has focused on doping of some functional nanomaterials or other materials into polymeric matrix to form functional nanofiltration composite membranes . It is obvious that there exists an issue that how nanoparticles are suitably dispersed into membrane matrix . We think that except for doping method, grafting functional polymer on the surface of porous membranes is a better strategy for obtaining functional membranes, which can effectively reject and remove the dye residuals.…”

Chloromethylated polysulfone (CMPSF) microfiltration membrane were first prepared by using immersion-precipitation phase transformation method, and then CMPSF membrane was modified into aminated PSF membrane (AMPSF membrane). A surface-initiating system of -NH 2 /S 2 O 8 2− was constituted at the interface between AMPSF membrane and a aqueous solution, in which monomer dimethylaminoethyl methacrylate (DMAEMA) and initiator ammonium persulfate were dissolved. The graft polymerization of DMAEMA was successfully realized on AMPSF membrane, resulting in the grafted membrane PSF-g-PDMAEMA. And then quaternization modification of the grafted membrane PSF-g-PDMAEMA was performed, resulting in the cationic microfiltration membrane of PSF-g-QPDMAEMA. The isothermal adsorption experiments of PSF-g-QPDMAEMA membrane for two acid dyes, reactive brilliant red (RBR), and reactive light yellow (RLY), were carried out, and the permeation experiments were also conducted. The experimental results show that PSF-g-QPDMAEMA membrane has strong adsorption ability for acid dyes by right of the electrostatic interaction between the quaternary ammonium cations on the surface of PSF-g-QPDMAEMA membrane and the sulfonate anions in the molecules of acid dyes as well as by right of cation-π interaction between the quaternary ammonium cations on PSF-g-QPDMAEMA membrane and the aromatic rings in the molecules of acid dyes. PSF-g-QPDMAEMA membrane displays excellent rejection and removing performance for acid dyes in water. POLYM. ENG. SCI., 60:900-908, 2020.
