81. Photorefractive liquid crystal-polymer dispersion with different morphology, H. Ono, H. Shimokawa, A. Emoto and N. Kawatsuki, J. Appl. Phys. 94 (2003) 23-30.


 The orientational photorefractive properties of the liquid crystal/polymer composites with different morphology are studied experimentally. The composites consist of the similar chemical components, but one shows phase-separated structure (polymer dispersed liquid crystal) and another one, miscible structure (polymer-dissolved liquid crystal composite). 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 morphology of the composites.
