Vogel-Fulcher-Tammann viscosity relation

The viscosity ( q)-temperature (T) relation of strong glass-forming liquids follows the Vogel-Fulcher-Tammann model [9] ... [Pg.417]

It is well known that the viscosity of a liquid decreases upon heating. This would usually be expected to fit to an Arrhenius type of behavior. That is, the natural logarithm of the viscosity should vary in a linear manner with temperature. All of the I Ls for which the temperature dependence of the viscosity has been studied deviate from this behavior [7, 9, 11, 14, 20]. Rather, they fit a Vogel-Tammann-Fulcher interpretation where the viscosity of the IL at any given temperature is better related to a material-specific temperature such as the difference between the temperatare of the study and the glass transition temperature of the IL. [Pg.440]
