Modulation of ion transport through nanopores in water desalination: a molecular dynamics study

Finely tuned water structure and transport in functionalized carbon nanotube membranes during desalination

“…In addition, the existence of -OH groups inside CNT could increase surface friction. [78][79][80] Therefore, -OH modication could produce adverse effect on water transport. The membrane-water interactions are slightly strengthened in both CH 3 -(7,7) CNT and F-(7,7) CNT membranes with the average energy values of −15.4 and −16.8 kJ mol −1 , respectively.…”

“…11,12 Within this context, developing biomimetic artificial channels is proposed to restore the function of biological channels and expand the application range for RO desalination through mimicking the structure of biological channels. 13–20…”

“…11,12 Within this context, developing biomimetic articial channels is proposed to restore the function of biological channels and expand the application range for RO desalination through mimicking the structure of biological channels. [13][14][15][16][17][18][19][20] Carbon nanomaterials, such as at-sheet graphene and carbon nanotubes, are good candidates to assemble the articial channels and replicate the structural features of biological membrane channels due to the inherent sub-nanometre size, hydrophobicity and atomically smooth tube walls. 14,21 Computer simulations and experimental studies demonstrated the extraordinarily high water permeability in carbon nanotube porins (CNTPs) with a single le water movement which was considered as the water conducting property of biological aquaporins (AQPs).…”
