1. A device comprising:
- an electrically switchable polymer film arrangement comprising a first surface side and a second surface side which are disposed opposite one another, the electrically switchable polymer film arrangement comprising;
at least one electrode pair comprising an anode and a cathode;
a polymer matrix; and
structuring particles disposed in the polymer matrix,wherein the polymer matrix and/or the structuring particles comprise an electroactive polymer, the first and/or second surface side being converted from a smooth state into a structured state by electrical switching of the electroactive polymer andwherein the structured state comprises elevations and depressions in the first and/or second surface side that reflect an electrode structuring and wherein the elevations or depressions reflect a distribution of the structuring particles.
