Recent advances in responsive photonic crystals and their applications in anti-counterfeiting solutions for the textile industry

Responsive photonic crystals (RPCs) have the advantages of visual response, controllable response speed, and reasonable response sensitivity, enabling them attractive in sensing detection, intelligent displays, anti-counterfeiting identification and other fields. At present, the rapid development of anti-counterfeiting technology ensures product quality and brand influence, as well as human health, placing an important economic value and bringing social benefits. This review introduces the research status of visual responsive photonic crystals, and the special attention is paid to the preparation principle, classification and preparation methods of RPCs, and their application progress in the anti-counterfeiting systems for the textile industry.
