Study of Nanoimprinting Plant Structures with Super Water Repellency

Abstract

The leaves of plants belonging to the Araceae family and to the Nelumbonaceae family, represented by the lotus leaf, are known to exhibit water repellency, a property attributed to a double roughness structure having nanostructures on the surface of the leaves. Past research efforts have examined biomimetic structures modeled on the structure of the lotus leaf. The present report presents the results of investigations of a lotus leaf structure transferred onto acrylic resin, made using a live plant as the original material instead of an engineered imitation. The results confirmed that the super water repellency derives from this structure.

Developing a Laparoscope Lens with Super Water-Repellent Antifouling Function using Biomimetic Materials

“…This has generated demand for laparoscopic camera objective lenses that offer antifogging and antifouling properties. Previously, we developed a biliary stent offering antifouling properties, which we realized by producing a biomimetic structure mimicking the structure of a snail shell and transferring it onto a resin surface [19][20][21][22][23][24][25]. This biomimetic structure is well-known for its oilrepelling effects in water (nanoscale ultrahydrophilic properties).…”
