In this review, we discuss the spontaneous pattern formation of sol­gel dip coating films induced by solvent evaporation, as a novel patterning technique. Linearly arranged striations and cell-like patterns were obtained upon withdrawing the substrate from the coating solution at increasing withdrawal rates. Such highly ordered micropatterns formed by the Bénard­Marangoni convection mechanism triggered by solvent evaporation. In contrast, dip-coating at rates below 1.0cm/min generated periodic stripe patterns arranged on the surface of the films that were perpendicular to the substrate withdrawal direction. Such a formation design was attributed to the onset of capillary flow of the coating solution at the meniscus induced by solvent evaporation.
