Surface topography has a first-order impact in most surface phenomena. One can name such phenomena as the lotus effect, which illustrates the influence of topography on wettability, or shark skin effect in which the texture improves water penetration. Many other application areas are less familiar to the general public but are very active in terms of research: in tribology, roughness influences the various regimes of lubricated friction. In physico-chemistry, adhesion phenomena can be controlled by topography. Other examples come from the field of fluid mechanics (sub-boundary layer, effects of turbulence) or thermal (parietal exchange coefficients). In electromagnetism, the reflection or absorption of waves can be influenced by the surface texture to allow rendering of color. Finally engineering perception, sensations of touch is highly dependent on the topography.
These disciplines can advance in the fundamental questions they rise as well as arise in the implied applications through a better understanding to the influence of topography. Moreover, the prospect of high speed texturing allows to consider industrial development. This cooperation between teams from these disciplines with specialist teams on advanced texturing techniques will allow to achieve the greatest advances.
