Light-induced shape recovery of deformed shape memory polymer micropillar arrays with gold nanorods
Abstract
Micropillars, made of light-responsive shape memory polymer with gold nanorods, were bent above its T g and cooled to lock the structures. Between bent and straight pillars, we demonstrated tunable transmittance and wetting.

The change in the films surface topography (bent or straight position of the micropillars) has a direct impact on the materials wetting and hydrophobic properties.
“This experiment proved that the change in the films surface topography (bent of straight position of the micropillars) has a direct impact on the materials wetting and hydrophobic properties (Fig. 11(b)).”

The shape recovery was accompanied by a switch of optical properties of the films from opaque (bent pillars) to transparent (straight pillars) and vice versa.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
