Abstract :
Ionic liquids (ILs) with interesting and useful
properties are usually organic salts which have an asymmetric
organic cation and a wide assortment of anions.
Mixing ILs and some materials like nano structures adjusts
their properties positively. This paper reviews the recent
computational molecular dynamics studies about mixture
of ILs and some materials including carbon nanotubes
(CNT), gases and water. Below we mention some reported
results in this review. In the case of ILs–CNT systems, we
review the behavior of ILs in the CNT dispersing. The
results show that ILs cannot disperse the bundled singlewalled
CNTs, but it can disperse some aggregated nonbundled
ones. In the case of confined water/IL mixtures,
the obtained results show that the most interaction energy
value is observed in pure water and pure IL systems. It was
shown in the case of absorption of gases such as SO2 by ILs
systems, that the diffusion coefficient of cation in the pure
ILs and IL/SO2 gas mixtures was greater than that of the
anions and much less than that of the SO2 molecules. In
addition, in comparison with pure ILs, the presence of SO2
leads to an increase in the diffusion coefficients, conductivity,
density and heat capacity of the ionic species of the
IL/SO2 gas mixtures.
