Decoupling exponent versus high-temperature activation free energy (IMAGE)
Caption
The relation between the decoupling exponent and the ratio of high-temperature activation free energies across a wide range of glass-forming liquids, including the Kob-Andersen model system, polymer-additive composites, linear polymer, charged polymers, star polymers, and knotted ring polymers. Data from over a dozen distinct systems collapse onto a single linear relationship, directly confirming that decoupling originates from differences in high-temperature activation free energies.
