LIQUID-CRYSTAL COMPOSITES: Multicolor Polymer-Dispersed Liquid Crystal (Adv. Mater. 7/2011)



original image

A composite consisting of a phase-separated porous polymer network and a liquid crystal that can change its structural color (covering the whole visible region) in response to temperature is reported by Yukikazu Takeoka and co-workers. The response is achieved by means of changes in both the diffraction properties and the wavelength dispersions of the refractive indices. on page 883
