| 研究開始時の研究の概要 |
The purpose of this research is the elucidation of the mechanisms by which flower petals turn transparent upon becoming wet. The petal microstructure most likely has air-filled voids that will be imaged by electron microscopy and a biomimetic version of the void structure will be prepared in polymer films. This process can be useful for the formation of reversibly transparent polymer films.

| 研究実績の概要 |
The transpareny change of flower petals has been successfully implemented in a biomimetic manner in porous thin films of a fluorinated polymer. The mechanism of the transparency change in the flower was elucidated using SEM and fluorecence micrsocopy. Air-filled spaces in the leaves can be filled with water, leading to the transparent state. Using a solvent exchange process in which a spin coated film of a solution of a fluorinated polymer was immersed in a non-solvent, porous polymer films were produced that show the same white-to-transparent optical change, which is completely reversible.
