Phys.org  July 14, 2023 Cholesteric liquid crystals (CLCs) are becoming increasingly popular due to their unique chiral structural color. Unlike ordinary CLCs materials, CLCs particles exhibit angle-independence, making them particularly noteworthy. However, currently, there are limited effective methods for controlling the structural color of CLCs particles, other than adjusting the concentration of chiral dopants or introducing stimuli-responsive groups. Researchers in Japan have developed a scalable and cost-effective process for preparing monodisperse CLCs particles via dispersion polymerization. By making CLCs into micrometer-sized monodisperse spheres, the helical pitch of CLCs could be varied according to its particle size, and the resulting structural […]
