Bionics – Nature as a Model
Nature is full of many different solutions. Micro- and nanostructured surfaces can be used to reproduce these functionalities.
Customized microstructures can be used to manipulate hydrophobic/hydrophilic surface characteristics (water-repellent or absorbing surfaces, Lotus effect) or oleophobic surface characteristics (oil-repellent surfaces, anti-fingerprint).
Appropriate surface patterning can reduce wind resistance of airplanes, cars or wind turbines, imitating the shark skin effect. Frictional resistance of interacting components can be decreased.
The reverse effect of highly adhesive surfaces (Gecko-effect) is also based on micro- and nanostructured surfaces.
