Relationship Between the Electro-Optic Performance of Polymer-Stabilized Liquid-Crystal Devices and the Fractal Dimension of Their Network Morphology



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.
