Randomized trial demonstrates enhanced infrared reflectivity and anti-counterfeiting in cholesteric liquid crystal films, suggesting advancements in security measures.
A three-layer broadband highly reflective PSCLC film is fabricated using PSNLC as an isolation layer. The film achieves >80% IR reflectivity, thermal insulation, and visible-region polarization-responsive anti-counterfeiting via chiral dopant tuning.
