Abstract

original image

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.
