Phys.org  May 30, 2024 Creating dual-mode patterns in the same area of the material increases the dimension of information storage and encryption security. However different patterns may lead to serious mutual interference in the process of manufacturing and usage. An international team of researchers (USA – Argonne National Laboratory, China) has demonstrated noninterfering dual-mode patterns by combining the structural color and chromatic polarization, which was designed with an azobenzene-containing linear liquid crystal copolymer featuring a photofluidization effect. The secondary imprinting was used to eliminate the partial damage to the structural color patterns during writing of the polarization patterns, thus obtaining […]
