|Abstract: ||The viscosity of (hexane + perfluorohexane) mixtures has been measured at 298 K, 303 K and 308 K, over
the whole composition range. The results show large negative deviations from the arithmetic mean of the
viscosities of the pure components, reaching
−17% at x(perfluorohexane) = 0.7. To obtain molecular level
insight into the behaviour of the system, all-atom molecular dynamics simulations have been performed
and used to calculate the viscosities, radial distribution functions, and rotational relaxation times of
the studied (hexane + perfluorohexane) mixtures. This is the first effort to assess the effect of mixing
hydrogenated and fluorinated molecules in the viscosity.|
