Dirk-Michael Drotlef, Lukas Stepien, Michael Kappl, W. Jon P. Barnes, Hans-Jürgen Butt and Aránzazu del Campo Insights into the Adhesive Mechanisms of Tree Frogs using Artificial Mimics Advanced Functional Materials 23
Studies in artificial tree-frog mimics show the benefits of the surface design (topography and hydrophilicity) for adhesion and friction under wet conditions. Capillary and direct-contact forces can be combined in patterned surfaces to enhance adhesion and friction performance in the presence of fluid films. Design rules for a new generation of artificial “wet” adhesives are presented.
