Leaf vein-inspired transparent superhydrophobic coatings with high stability
Transparent superhydrophobic coatings hold significant potential for applications in architectural glass and optoelectronic devices. However, obtaining good compatibility between highly transparent, low haze and excellent mechanical stability in a superhydrophobicity coating remains a significant challenge. Inspired by the natural protection mechanism of the hierarchical structure of leaf veins, we have designed and fabricated transparent superhydrophobic coatings with highly detailed hierarchical vein-like ridges via a template-assisted multi-mask photolithography and inverted mold process combined with a spraying technique. The coated glass exhibited not only outstanding superhydrophobicity, with contact angle ⩾ 160° and sliding angle ⩽ 1.5° but also a high optical transmittance of 88.4% and a low haze of 8.1%, as well as remarkable mechanical durability and weather resistance.
期刊介绍：
Science China Materials (SCM) is a globally peer-reviewed journal that covers all facets of materials science. It is supervised by the Chinese Academy of Sciences and co-sponsored by the Chinese Academy of Sciences and the National Natural Science Foundation of China. The journal is jointly published monthly in both printed and electronic forms by Science China Press and Springer. The aim of SCM is to encourage communication of high-quality, innovative research results at the cutting-edge interface of materials science with chemistry, physics, biology, and engineering. It focuses on breakthroughs from around the world and aims to become a world-leading academic journal for materials science.
