ELECTROOPTICS OF LIQUID-CRYSTAL COMPOSITES BASED ON POLYMETHYL METHACRYLATES

The electro-optical properties of liquid-crystal (LC) composites-polym eric materials in whose pores nematics are found-are investigated. The dependence of the sample transmittance on the voltage and the turn-on and turn-off times are measured at different temperatures. The unique features of the initial portions of the transmission curves are point ed out for samples with large capsules. The dependences of the dischar ge time of a capacitor with an LC composite on the concentration of ne matic material and the capsule size are considered.
