摘要
A quantitative relationship is established between the electro-optic performance (reflectivity, transmittance, threshold field, response time) of a polymer-stabilized liquid-crystal and the network morphology of the cholesteric textures (see Figure). By analysis of independent preparation series, varying curing temperature, UV intensity, and irradiation time, respective scaling relations are proposed.
