Anticounterfeiting photonic bilayer films were fabricated by sandwiching two solid-state cholesteric liquid crystal films having different handedness. The fabricated photonic bilayer films were successfully applied to patterning by selective photopolymerization. This photonic bilayer film as a new cryptographic technology is of interest for its anticounterfeiting application.
通过将两个具有不同手性的固态胆甾相液晶膜夹在一起制备了防伪光子双层膜。制备的光子双层膜通过选择性光聚合成功应用于图案化。这种作为一种新的加密技术的光子双层膜因其防伪应用而备受关注。
