Content

Three-dimensional (3D) micropatterning of surfaces signifies a recent paradigm change for control of surface functionalities: the exploitation of cleverly designed surface protrusions, “fibrils” and other features at the micron scale – as in insects, spiders and geckos – to create fundamentally new degrees of freedom for mechanical and other surface functions. The current emphasis is on controlling adhesion and friction, which is of great potential interest in microfabrication, biomedical industry, construction industry, and sports equipment. This talk will summarize the recent developments in producing bio-inspired micropatterned polymer surfaces:
i) fundamental effects of feature size, shape and materials parameters,
ii) design of active surfaces that exploit a transition from an adhesive to non-adhesive state, and
iii) a new approach to medical adhesives based on the “gecko” effect.
The overall objective is to develop, by experiment and theory, new micropatterned surface materials with innovative properties, e.g. for active adhesive, medical, optical and tactile (haptic) functions.

 

Prof. Dr Eduard Arzt is scientific director and chairman of INM – Leibniz Institute for New Materials in Saarbrücken, Germany, and Professor for New Materials at Saarland University. A native of Austria, he studied physics and mathematics at the University of Vienna, Austria, and obtained his PhD there in 1980. After a postdoctoral fellowship at Cambridge University, UK, he led a research group at the Max Planck Institute for Metals Research in Stuttgart, Germany. In 1990, he became Max Planck director with a joint appointment as Professor of Metals Physics at the University of Stuttgart. The Institute for Scientific Information lists him as a highly cited materials scientist.
