Two-Way Rewritable and Stable Photonic Patterns Enabled by Near-Infrared Laser Responsive Shape Memory Photonic Crystals

Abstract

Shape memory photonic crystals (SMPCs), which integrate two distinctly scientific areas of photonic crystal and shape-memory polymer, have great potential in advanced optical devices, sensing and displays etc. Despite recent progresses in SMPCs, the contact-stimuli during recovery limit their practical application. Here, a new type of near-infrared laser responsive SMPCs is reported. Those SMPCs exhibit high optical reversibility, excellent stability, and the direct-pressure-induced programming and near-infrared laser (980 nm) triggered recovery capabilities, due to the presence of polyurethane units, reversible plastic deformation and photothermal effect. By taking advantages of these characteristics, various rewritable and stable photonic patterns can be created by imprinting lithography and near-infrared laser writing. Importantly, the photonic membrane exhibit two-way rewritable capability on which the photonic patterns can be created twice in one write/erase cycle. Given the striking color changes associated with the reversible photonic microstructure transitions during programming and recovery, this work provides a facile and versatile platform for multifunctional sensing, display, and anticounterfeiting.
