Paper Abstract

Effects of curing temperature and UV intensity on electro- optic properties of polymer stabilized cholesteric texture reverse-mode light shutters have been studied. Scanning electron studies indicate that increasing the curing temperature generally results in a larger average mesh size within polymer networks. The cell polymerized at correspondingly low temperature has a stable OFF state (planar texture) while the driving voltage is high. Increasing the curing intensity results in a more dense network and the strands are smooth and thin. The cells prepared with low UV intensity exhibit high contrast and low driving voltage, while the response time is slower than those prepared with high UV intensity.
