Abstract
AbstractUbiquitous surface wrinkling has been well‐studied theoretically and experimentally. How to modulate the stress state of a liquid‐supported system for the unexploited wrinkling capabilities remains a challenge. Here we report a simple linearly‐polarized‐light illumination to spatiotemporally trigger ultrasensitive in situ dynamic wrinkling on a floating azo‐film. The smart combination of the liquid substrate with photoresponsive azo‐moieties leads to the light‐induced ultrafast wrinkling evolution, accompanied by unprecedented sequential wrinkling orientation conversion (from polarization‐parallel to polarization‐perpendicular). The involved different polarization‐dependent sequential photo‐orientation for azo side chains and azo‐grafted main chains of azopolymers is disclosed experimentally for the first time. Meanwhile, programmable dynamic wrinkling with all‐optical switchable surface topographies is available, which has wide application potentials in photoresponsive soft photonics.
