摘要： Synthetic brochosomes can be prepared by disposing a monolayer of first polymer microspheres on a substrate and forming a layer of metal on the monolayer of the first polymer microspheres. A monolayer of second polymer microspheres is then disposed on the layer of metal to form a template. The second polymer microspheres are smaller than the first polymer microspheres. A brochosome material is then electrodeposited on the template. The brochosome material is selected from the group consisting of a metal, a metal oxide, a polymer or a hybrid thereof. The first polymer microspheres and the second polymer microspheres are then removed to form a coating of synthetic brochosomes of the brochosome material on the substrate.

摘要： Substrates having a textured surface that can maintain or improve droplet mobility in both the Cassie and Wenzel states include a textured surface and a conformal lubricant layer thereover. The textured surface can include a plurality of raised first elements and a plurality of second elements thereon and the conformal lubricant layer over the plurality of raised first elements and covering the plurality of second elements. The plurality of raised first elements can have an average height of between 0.5 μm and 500 μm, and the plurality of second elements can have an average height of between 0.01 μm and 10 μm. Such substrates can be prepared by texturing a surface of a substrate with a plurality of raised first elements and a plurality of second elements thereon; optionally silanizing the textured surface and applying a lubricant layer over the plurality of raised first elements and between the plurality of second elements.

摘要： A substrate with a switchable surface has been developed that can rapidly switch its surface character such as between two distinct liquid-repellent modes: (1) a superhydrophobic mode and (2) a slippery mode. Such surfaces have demonstrated adaptive liquid repellency and water harvesting capabilities.
