| Outline of Research at the Start |
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.
|
| Outline of Annual Research Achievements |
In 2022, we have achieved the following results. Inorganic salts have been incorporated in flower petals by immersion in salt solutions. The flower petals were observed by electron microscopy and energy dispersive spectroscopy.

| Current Status of Research Progress |
Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
Because of the travel restrictions caused by SARS-CoV virus, the measurements at the collaborator institute in Germany has been delayed.
|
| Strategy for Future Research Activity |
In fiscal year 2023, we plan to visit the collaborator in Germany and present the results at a international conference.
