Selectivity of Carbon Nanotubes under An Electric Field on Transferring Water - Alcohol Mixtures

研究成果: Conference article

抜粋

Carbon nanotubes (CNTs) have shown a great promise for nanofluidic-based applications such as for separation membranes. Water confined in nanotubes has different properties compared with those in bulk. Therefore, to develop a membrane with CNTs, it is very important to clarify the behavior of water in CNTs. In this study, we show effects of an electric field on water in a CNT by molecular dynamics simulation. An electric field aligns the dipole moment of water molecules and induces formation of an ordered structure in a CNT. As a result, the electrostatic interaction between water molecules within the structure becomes stronger. Strengthening of the electrostatics interaction facilitates water molecules preferring to fill a CNT over alcohol molecules. This indicates a strong separation effect for water-alcohol solutions.
