Robust photonic microcapsules are created by microfluidic encapsulation of cholesteric liquid crystals with a hydrogel membrane. The membrane encloses the cholesteric core without leakage in water and the core exhibits pronounced structural colors. The photonic ink capsules, which have a precisely controlled bandgap position and size, provide new opportunities in colorimetric micro-thermometers and optoelectric applications.
通过微流控技术将胆甾相液晶封装在水凝胶膜内，制备出了稳定的光子微胶囊。该水凝胶膜封装的胆甾相核心在水中不会发生泄漏，并且微胶囊的核心表现出明显的结构色。这种具有精确控制的带隙位置和尺寸的光子墨水胶囊，为比色微温度计和光电应用提供了新的机会。
