| Research Abstract |
We suggested the spontaneous pattern formation induced by Benard-Marangoni convection as a novel patterning process of sol-gel-derived ceramic films. Cell-like micropatterns were spontaneously formed on the surface of silica films prepared via dip-coating process, where the surface patterns were linearly arranged parallel to the substrate withdrawal direction. Such highly-ordered micropatterns were achieved by Benard-Marangoni convection and the unidirectional flow of the coating solution on the substrate during dip-coating. We found that the size of the cell-like patterns induced by Benard-Marangoni convection increased with increasing coating temperature and surface tension of coating solutions. Moreover, novel pattern formation induced by capillary force was observed with decreasing substrate withdrawal speeds. These results are beneficial for the development of novel self-organization triggered by solvent evaporation.
