Dynamic anticounterfeiting and tunable lasing with screen-printed cholesteric liquid crystal elastomers

Proceedings of the National Academy of Sciences, Volume 123, Issue 12, March 2026. <br/>SignificanceThis research presents a scalable screen-printing strategy for fabricating dynamic structural-color graphics using cholesteric liquid crystal elastomers (CLCEs). The printed patterns exhibit circularly polarized reflection, mechanochromism, …
