Abstract

“Lycurgus cup” effect, referring dichroism between reflection and transmission modes of the same structures, is a peculiar phenomenon of multi-faceted display in structural color. Beyond the static dichrotic display, the realization of dynamic dichroism desires active materials and tunable structures, and owns the great demand from smart display, anti-counterfeiting and environmental sensing. We hereby propose a metal-hydrogel-metal (MHM) nanocavity for dynamic dichrotic display. This structure includes thin silver layers to induce the partial transmission with the existing reflection, and a polyvinyl alcohol (PVA) hydrogel layer owning the swelling/deswelling deformability to humidity change. The following experimental measurements and theoretical analysis prove that the reflection and transmission modes exist at distinct wavelengths, and the swelling hydrogel layer by humidity change between 10 and 90% RH can dynamically modulate the dichrotic resonance with the wavelength shift over 100 nm. Such environmental-sensitive and real-time tunable dichroism with hydrogel-based structural color is then verified for multi-color printing, resolution test, and cycling test.

基于湿度响应金属-水凝胶-金属纳米腔的动态透射-反射二色性
“莱库格斯杯”效应是指同一结构的反射和透射模式之间的二色性,是结构色彩中多面显示的一种奇特现象。在静态二色显示之外,动态二色的实现需要活性材料和可调结构,并且具有智能显示、防伪和环境传感的巨大需求。我们在此提出了一种用于动态二色显示的金属-水凝胶-金属(MHM)纳米腔。该结构包括薄银层和聚乙烯醇(PVA)水凝胶层,前者可以诱导现有反射的部分透射,后者对湿度变化具有溶胀/溶胀变形能力。接下来的实验测量和理论分析证明了在不同的波长处存在反射和透射模式,并且在10 ~ 90% RH的湿度变化下膨胀的水凝胶层可以动态调制波长位移超过100 nm的二向色共振。这种具有环境敏感性和实时可调的水凝胶结构色二色性,然后在多色印刷、分辨率测试和循环测试中得到验证。
