| Outline of Final Research Achievements |
We improved the spontaneous pattern formation induced by Benard-Marangoni convection triggered by solvent evaporation. Here, we attempted to control more precisely the pattern size by the molecule design of the precursor materials of sol-gel-derived ceramic films. Cell-like patterns of 1.0-1.5 μm in height and of ca. 20 μm in width were spontaneously formed on the surface of ceramic films prepared by sol-gel dip-coating process. We found that the size of the cell-like patterns induced by Benard-Marangoni convection increased with increasing molecule size of the precursor mateirals, which could be caused by the higher surface tension. Moreover, novel pattern formation was observed on ceramic films obtained from metal-acetylacetonate complexes, where dendrite patterns formed with decreasing substrate withdrawal speed. These results are beneficial for the development of novel self-organization triggered by solvent evaporation.
