Abstract
In this study, Molecular Dynamics (MD) simulations are employed to observe the effect of different chain lengths on density, self-diffusion coefficient and viscosity of [Cnmim][TF2N] ionic liquids (ILs). Both density and self-diffusion coefficient decrease as the chain length increases. The rheological curves show a shear-thinning after Newtonian behavior. The results suggest that viscous thinning is related to the decrease in the number of hydrogen bonds (H-bonds) and the alignment of the alkyl chains in the flow direction. Viscosity values at zero-shear-rate increase as the chain size does. Moreover, the static structure factor indicates anisotropy in systems with cation alkyl chains of 6 and 8 carbon atoms. However, in a 10 carbon atom cation alkyl chain, a more ordering is observed.
