In nature, rice leaves exhibit special anisotropic sliding capabilities. Although researchers have succeeded in fabricating artificial rice leaf structures and realizing the wettability function of the leaf surface, these methods used to date are complex and do not allow the fabrication of surfaces with large area. Herein, we adopted a simple technology -two steps soft transfer to fabricate biomimetic rice leaf. The fabricated surface well reproduced the structures of the rice leaf surface and exhibited a static superhydrophobic property similar to that of the real rice leaf surface. In terms of its dynamic wettability, it clearly exhibited an anisotropic sliding property. Systematic measurements showed that the sliding angles parallel and perpendicular with the vein direction were 25° and 40°, respectively. The method was simple and reliable, without the need for expensive instruments and complex technologies, which could be used for the rapid fabrication of large-area artificial rice leaf surfaces. We believe that the artificial rice leaf surface fabricated by this method has great potential applications in biomimetic functional surfaces, microfluidics, and so on.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
