摘要：
We demonstrate here the experimental evidence that a stripe pattern having a local orientational order appears for a phase-separating symmetric fluid mixture confined in quasi two dimensions. This local parallel arrangement of bicontinuous tubes is probably induced by (i) the spatial symmetry breaking of a bicontinuous pattern due to the geometrical confinement and (ii) the interface tension that favors tubes with a straight rodlike shape. Confinement into quasi two dimensions is likely prerequisite for this unusual ordering phenomenon. This could be the rare example of phase separation with a stripe pattern for simple binary mixtures having no long-range repulsive interaction. We also show the discrete nature of the elementary coarsening process of bicontinuous phase separation.
