Scaled structures in late stages of microphase separation of binary paraffin mixtures

Since the dynamic properties in paraffin mixtures are different from those in alloys and polymer blends, paraffin mixtures are believed to be another class of substances establishing the "universality" of the dynamical scalin g behavior of phase separation. In this paper, the scaled structures of mic rophase separation in paraffin mixtures are described using a scaling funct ion based on a two-phase model with kinetics based on the Cahn-Hilliard equ ation. It has been demonstrated that at the late stages of the microphase s eparation the scaling behavior in the paraffin mixtures agrees well with th e universal features predicted by the scaling function. The scaled structur es of microphase separation in paraffin mixtures can be directly calculated from the volume fraction of the minority phase without any adjustable para meter.
