The thermodynamic competition is thus between a monophasic, water-rich mixture of DIPA that includes the micelles, and a biphasic liquid-liquid mixture. In the biphasic liquid mixture, a DIPA-rich phase is in equilibrium with a macroscopically separate water phase. The phase-separated state has higher entropy because the DIPA phase is much more disordered and has more rotational dynamical degrees of freedom. At high enough temperature, the loss of the O-H-N hydrogen bonds on phase separation is compensated by the increased entropy of phase separation, and the phase-separated state is preferred.
