Thermally Induced, Multicolored Hyper-Reflective Cholesteric Liquid Crystals

Thermally Induced, Multicolored Hyper-Reflective Cholesteric Liquid Crystals

A dynamic multicolored cholesteric cell is formed using chiral, structured, surface‐tethered polymer networks. The multicolored cholesteric cell is filled with a thermally tunable liquid crystal mixture of opposite handedness of the polymer networks, which enables thermally induced hyper‐reflectivit...

Zusammenfassung:A dynamic multicolored cholesteric cell is formed using chiral, structured, surface‐tethered polymer networks. The multicolored cholesteric cell is filled with a thermally tunable liquid crystal mixture of opposite handedness of the polymer networks, which enables thermally induced hyper‐reflectivity at the two reflection bands induced by the surface tethered polymer.
