Free-energy function, glass-forming liquids

By performing calorimetry during complex formation it has been found that the enthalpy of complex formation of systems that form glass-like phases has an opposite sign to the enthalpy of systems that form liquid-like phases, i.e., the formation of glass-like phases is exothermic and the formation of liquid-like phases is endothermic. The free energy (AfG), enthalpy (Af//) and entropy (Af5) of polyelectrolyte complex formation and how they vary as a function of the ionic strength will be discussed.
