Rose petals have both high water repellency and adhesiveness to water droplets, and are expected to be applied to droplet control and other applications. Its surface consists of a hierarchical structure of micro and nano structures. In this study, microstructures were fabricated using photolithography on a nanostructured moth-eye mold, and the wettability of the transfer film was investigated. With this method, the size and design of the microstructure can be easily changed by modifying the photomask design.
