86. Effects of droplet size on photorefractive properties of polymer dispersed liquid crystals, H. Ono, H. Shimokawa, A. Emoto and N. Kawatsuki, Polymer, 44 (2003) 7971-7978.


Effects of liquid-crystal droplet size on orientational photorefractive properties of the polymer dispersed liquid crystals are investigated experimentally. The composites consist of the same chemical components, but the liquid crystal droplet size was varied by controlling the fabrication process. Particular attention is given to the observation and qualitative and/or quantitative modeling of the resolution, dependence of the applied dc field, dynamics of grating generation and photocurrents, which is strongly dependent on the liquid crystal droplet size.
