| Outline of Final Research Achievements |
We prepared a slurry which consisted arbitrary-shaped microparts and deionized (DI) water, and evaluated the self-arrangement properties of the microparts, to fabricate periodic structures on a relatively large area. Hexagonal cylinder-shaped microparts were fabricated using polydimethylsiloxane. The diameter and height of the hexagonal cylinder-shaped microparts were 20 μm and 10 μm, respectively. The slurry was prepared by dispersing the microparts into DI water. The self-arrangement properties were evaluated on both hydrophilic and hydrophobic treated glass substrates. When the 10 μL of the slurry was fallen in drops on the hydrophilic substrates, the microparts were partially self-arranged to form close-packed structures. In contrast, the microparts were successfully self-arranged on the hydrophobic substrates to form close-packed structures on larger area.
