Periodic spinodal decomposition in a binary polymeric fluid mixture.

摘要: We demonstrate here a dynamic phase transition between periodic state without coarsening and nonstationary with coarsening, for binary polymer mixture periodically driven above below its instability point. For we have found, in both symmetric off-symmetric mixtures, the growth of two-level structure characterized by two length scales. There is no self-similarity this pattern evolution. A diagram stability has been obtained first time: Hydrodynamic interaction found to strong effect on limit through dependence composition symmetry.
