This research demonstrates enhanced strain-sensing capabilities in cholesteric liquid crystal elastomers, suggesting applications in anti-counterfeiting.
Cholesteric Liquid Crystal Elastomers This cover features a porous cholesteric liquid crystal elastomer (CLCE) engineered with a femtosecond laser and coated with quantum dots. Under mechanical stress, the material exhibits a vivid, sensitive dual-color response. This interplay between the CLCE's structural color and quantum dots' photoluminescence creates a strikingly visual strain-sensing system, offering potential in advanced anti-counterfeiting applications.
