Recent Progress in Responsive Structural Color

Structural color has been regarded as an ideal alternative to pigments because ofthe advantages of environmental friendliness, resistance to fading, and dynamic regulation.Responsive structural color can give real-time visible feedback to external stimuli and thus hasgreat prospects in many applications, such as displays, sensing, anticounterfeiting, informationstorage, and healthcare monitoring. In this Perspective, we elucidate basic concepts,controllable fabrications, and promising applications of responsive structural colors. Inparticular, we systematically summarize the general regulation mode of all kinds of responsivestructural color systems. First, we introduce the basic chromogenic structures as well as theregulation modes of responsive structural color. Second, we present the fabrication methods ofpatterned structural color. Then, the promising applications of responsive structural colorsystems are highlighted in detail. Finally, we present the existing challenges and futureperspectives on responsive structural colors.

Automated summary

This article introduces the basic concepts, fabrication methods, and promising applications of responsive structural colors. It systematically summarizes the regulation modes of various responsive structural color systems and highlights the fabrication methods of patterned structural colors and their potential applications.
