Abstract
New Polymer Dispersed Liquid Crystal (PDLC) materials were prepared by a Polymerization Induced Phase Separation (PIPS) mechanism using U.V. radiation. The samples are obtained from the liquid crystalline mixtu re E7 and a blend of monofunctional (2-Ethyl Hexyl Acrylate) and difun ctional (1,6-Hexane Diol DiAcrylate) monomers as precursors of the mat rix. The thermodynamic properties of both cured and uncured samples we re studied by Differential Scanning Calorimetry and Optical Microscopy . The optical transmission of selected PDLC films has been measured as a function of frequency and amplitude of the applied voltage for seve ral film thicknesses.
