Integrated sensing from the synergetic color change of the center/brush of cholesteric liquid crystal particles

Cholesteric liquid crystal (CLC) particles can adaptively respond to constant changes in external stimuli and thus are widely used solvent-sensing, pattern fabrication, anti-counterfeiting. Previous studies discussed the color change at center of for various applications. However, few analyzed brush structure response applications because complicated birefringence effect. In this paper, we present a novel integrated sensing system based on synergetic from CLC particles. This provides abundant additional information relative traditional system. prepared by mixing reactive mesogens, chiral dopant, non-reactive LC molecule, photoinitiator using microfluidic device subsequent photopolymerization. The exhibit gorgeous upon solvent Bragg reflection effect, which is explained possible color-changing mechanism introduced paper. For proof-of-concept applications, such polymer demonstrated multi-solvent-sensing detection display. study new insights into development stimuli-responsive advanced functional materials with tailorable nanostructures toward technological ranging
