Objectives

The objective of the course is to establish the relationships between surface functionality and surface morphology, in a biomimicry approach. In terms of surface functionality, the focus will be on the wettability and optical properties of natural textured surfaces. The course should develop knowledge in biomimicry and bio-inspiration of surfaces by offering a description of biological surfaces in terms of morphology and surface chemistry. The morphology and chemistry of plant and animal surfaces will be studied in detail. The morphology/chemistry/wettability relationships of these surfaces will be the focus of this training action. The physics of wetting and adhesion will be studied in detail. The different wettability models will be presented both from a classical point of view through contact area approaches and in a more original way through the triple line approach. The optical properties of textured biological surfaces will be studied through the notion of structural color.
