Femtosecond laser functionalized surfaces inspired by nature
- Nature has continuously inspired science when practical problems need to be solved in a functional and efficient way. The challenge for researchers usually consists in the transfer of such biological functionalities to diverse types of technical materials with the available processing technologies. In this regard, femtosecond laser-based approaches offer a large flexibility to modify virtually any material (metals, semiconductors and dielectrics), provide the ability to work under different environment conditions (air, vacuum or reactive atmospheres) and when combined with the proper optics, they offer exceptional spatial resolutions that could be used to mimic effectively very complex functionalities. In the particular case of surface processing, lasers have been proven feasible to functionalize materials by customizing its optical properties, chemical composition and surface morphology in a controllable way and in some cases at industrially relevant speeds. In this work, we present aNature has continuously inspired science when practical problems need to be solved in a functional and efficient way.

In this work, we present a selection of technical applications based on surface modifications in the form of laser-induced periodic surface structures (LIPSS) to tailor the material properties for utilization in optics, fluid transport, wetting control and tribology.…
