The Effect of Cation Type and Temperature on the Transport Properties of Some Room Temperature Ionic Liquids

In this paper the viscosity and electrical conductivity of four different ILs have been calculated using molecular dynamics simulation at different temperatures. As it was expected, the enhancement of temperature makes a decrement in the viscosity and increment in electrical conductivity of the studied ILs. From the simulated properties, it is concluded that the main effective parameter in the viscosity of the cholinium-based ILs is the spherical hindrance. While, the intermolecular interaction is the domain effect in the viscosity of the ILs containing imidazolium cation.
