Functionalized surfaces can be obtained by fabricating deterministic or stochastic structures with features in the micrometer, submicrometer and nanometer range. However, significantly enhanced surface properties can be produced by using micrometer scaled features covered by nano- or sub-micrometer structures, which occurs typically in nature. The main objective of this project is to develop new concepts and strategies for the fabrication of advanced functionalized surfaces based on topographical surface patterns with a multiscale characteristic as well as understanding the effects of two and three-level multiscale patterns on surface properties. To attempt this main objective, different laser based structuring methods will be combined. Furthermore, the developed technologies will be also used to produce structured metallic stamps for roll-to-roll processes, permitting to achieve record fabrication speeds up to 10 m²/min. The systematic variation of the surface topographical characteristics in a controlled and precise way will not only allow gaining significant knowledge in the field of surface engineering, but also opening a wide spectrum of opportunities for several industries (e.g. automobile, medical, food industry, pharmaceutical), all of them requiring advanced functionalized surfaces.

功能化表面可以通过制造具有微米、亚微米和纳米级特征的确定性或随机结构来获得。然而，通过使用纳米或亚微米结构覆盖的微米尺度特征可以产生显着增强的表面性能，这在自然界中通常发生。该项目的主要目标是为基于具有多尺度特征的地形表面图案的高级功能化表面的制造开发新的概念和策略，以及了解二级和三级多尺度图案对表面性质的影响。为了实现这一主要目标，将结合不同的基于激光的结构方法。此外，开发的技术还将用于生产用于卷对卷工艺的结构化金属印章，允许实现创纪录的制造速度高达10 m²/min。以可控和精确的方式系统地改变表面形貌特征，不仅可以在表面工程领域获得重要的知识，而且还可以为几个行业（例如汽车，医疗，食品工业，制药）提供广泛的机会，所有这些行业都需要先进的功能化表面。
