From bioinspired structure formation to mechanotunable metamaterials — •Andreas Fery — Leibniz Institut für Polymerforschung Dresden e.V, Institute of Physical Chemistry and Polymer Physics; Hohe Str. 6, 01069 Dresden — Technical University Dresden Chair for Physical Chemistry of Polymeric Materials

Wrinkling is widely encountered in nature and can even result in sub-micrometer periodic features e.g. on flower petals. Understanding the physics of wrinkling allows harnessing the process for structure formation in a non-biological context and for metrology of thin film mechanics. The latter is especially interesting for 2D materials and I discuss recent examples including the extension of this work to strain engineering of 2D materials. Controlled wrinkling for structure formation on the other hand offers interesting opportunities for scalable surface patterning. I will discuss the use of wrinkling templates for the formation of particle based metamaterials.

Keywords: wrinkling; metamaterials; 2d materials; metrology; strain engineering
