Preparation and electric optical property of polymer dispersed liquid crystal devices

To explore the technological feasibility of the intelligent chameleon camouflage material, polymer dispersed liquid crystal (PDLC) devices were prepared by the light induced phase separation method. Effects of the polymer content on the morphology and the electric optical properties of PDLC devices were studied. The influence of the device thickness on the electric optical properties of PDLC devices was also investigated. Results indicate that the PDLC devices with the polymer content of 40% and the device thickness of 9.8 μm could work with a low voltage, high contrast and stability, and guide the fabrication of the flexible chameleon camouflage material. PDLC has a potential application in the display, sensor, optic electronic switch, optical grating and other new analytical devices.
