| Outline of Final Research Achievements |
Two layered sheet material was prepared for hot embossing process, which can form micro pattern not only on the surface but also the interface between the layers. In this work, two kinds of mold were applied for the layered sheet material to fabricate a multi-scale surface structure. Only molds with simple patterning were needed for the process. The multi-scale surface structure can be found in nature, such as on a lotus leaf, which is famous for its super-hydrophobic surface. The fabricated multi-scale surface structure in the present work showed higher hydrophobicity than simple micro-patterned surface.
