Functionalized carbon nanotube (CNT) membrane: progress and challenges

Abstract

Various approaches have been investigated to functionalize CNT for achieving a high dispersion of CNT as well as high compatibility between CNT and polymer matrix which lead to improvement of membrane properties and performances.

Effects of acid, alkaline, and seawater aging on the mechanical and thermomechanical properties of glass fiber/epoxy composites filled with carbon nanofibers

“…Table shows the elemental composition (obtained from EDS) of CNF surface before and after acid aging, which indicates an increase in oxygen on the CNF surface due to oxidation. Surface hydrophilicity of the CNFs may be enhanced due to this oxygen containing functional groups, which in turn increases the water affinity and thus causes an accelerated degradation in the mechanical properties of the CNF‐GE composites during acid aging.…”

Anti-biofouling effect of a thin film nanocomposite membrane with a functionalized-carbon-nanotube-blended polymeric support for the pressure-retarded osmosis process

“…[17][18][19][20] In this purpose, the functionalized CNT was embedded in the polyamide thin lm during interfacial polymerization or additional coating. [22][23][24] Nevertheless, few studies have described carbon nanotubes employed in the TFC membrane for PRO process. In this study, the CNTs incorporated in the support layer of TFN membranes was analyzed to determine their anti-biofouling ability in the PRO mode for potential applications of the PRO process.…”

Composite Electrodes of Activated Carbon and Multiwall Carbon Nanotubes Decorated with Silver Nanoparticles for High Power Energy Storage

“…Carbon black [23,24] and multiwall carbon nanotubes (MWCNTs) [25][26][27][28] are commonly used to increase the electrical conductivity of composite coatings in supercapacitors [23,25,26,28] and batteries [24] or in composite interlayers between the electrode and current collector [29,30]. Furthermore, carbon nanotubes may be further functionalized to become compatible with the electrolyte solvent, such as -COOH functionalized MWCNTs to become hydrophilic for aqueous electrolytes [31] or compatible with polar electrolyte solvents such as acetonitrile [32] or patterned [33] to be compatible with the polymer binder used in the electrode coating, such as gelatin, polyvinyl alcohol (PVA) or PEDOT:PSS.…”
