Research interests cover plant biodiversity, especially systematics and phylogeny of Aristolochiaceae and Piperaceae as well as biomechanics and functional morphology. He is also director of the Botanical Garden, and from 2006 to 2012 he was appointed Speaker of the Department of Biology. Since 2014, he has been deputy head of the Program Division Functional Microstructures at Leibniz Institute for New Materials Saarbrücken, Germany.Ĭhristoph Neinhuis holds the chair for botany at TU Dresden. He has obtained the International Bionic Award 2014 from VDI for his PhD thesis on free-standing polymer membranes for omniphobic and mechanically stable surface coatings. He was a fellow of the DFG Research Training Group 1401/2 at the TU Dresden and did his doctorate at the Leibniz Institute of Polymer Research Dresden (IPF) and the Max Bergmann Center of Biomaterials Dresden (MBC). The current understanding of the underlying principles and approaches to their technological implementation are summarized and discussed.ĭr René Hensel studied materials science at the TU Dresden, Germany. ![]() In particular, the resistance against complete wetting and the mechanical stability strongly both depend on the topographical features of the nano- and micropatterned surface. Based on the obtained liquid repellence of a variety of liquids with remarkable efficiency, the review provides general design criteria for robust omniphobic surfaces. In particular, we focus on springtails presenting an overview on the cuticular morphology and chemistry and their biological relevance. In this review, we report on the liquid-repellent natural surfaces of arthropods living in aqueous or temporarily flooded habitats including water-walking insects or water spiders. Springtail cuticle-derived surfaces therefore promise to overcome limitations of lotus-inspired surfaces (low durability, insufficient repellence of low surface tension liquids). The wingless arthropods evolved a highly textured, hierarchically arranged surface pattern that affords mechanical robustness and wetting resistance even at elevated hydrostatic pressures. One example is the water and even oil-repellent cuticle of springtails (Collembola). Omniphobic surfaces found in nature have great potential for enabling novel and emerging products and technologies to facilitate the daily life of human societies. ![]()
