Photoprogrammable Moisture-Responsive Actuation of a Shape Memory Polymer Film

Jieying Xue et al.

Summary: This study reports on a method to achieve programmable humidity-responsive actuating behaviors by introducing photoprogrammable hygroscopic patterns into shape memory polymers. The researchers found that by treating the polymer surface to form an Fe3+-carboxylate coordinating network, transient hygroscopic gradients can be generated under UV light, driving the deformation of the polymer. Furthermore, the shape memory effect can be effectively used to adjust the direction and amplitude of the moisture-driven actuating behavior.

Near-Infrared Light-Driven Three-Dimensional Soft Photonic Crystals Loaded with Upconversion Nanoparticles

Yaqi Qiu et al.

Summary: This study demonstrates the near-infrared light-driven reversible and dynamic photonic bandgap modulation of soft photonic crystal through the integration of core-shell upconversion nanoparticles and a novel molecular photoswitch. The intensity ratio of UV/vis luminescence emitted by the UCNPs can be controlled by changing the excitation power, leading to red-shift and blue-shift of the photonic reflection. This work provides new insights into the fabrication of 3D photonic nanostructures with tailorable functionalities for soft-matter photonics and integrated communication technologies.
