LC Alignment through Photoactive Surface Layers

Manipulation of LC Alignment through Photoactive Surface Layers 

A closely related phenomenon induced by linearly polarized light was found independently by Gibbons et al., who employed a polyimide (PI) film doped with azobenzene molecules as a dichroic dye and showed that the direction of homogeneous 

Modulation of Light Waves in Polymer/LC Composite Films 

Although such polymer/LC composite films are usually prepared by emulsification and phase separation techniques, the resulting composites have a variety of morphological characteristics arising from differences in conditions and compositions during sample preparation. The polymer/LC composite films are mainly classified into four types  

Currently, to develop more highly functionalized LC devices, intensive studies are being carried out on electrically controllable polymer/LC composite films with such advantageous features as high electric field response, high contrast, and wide viewing angle, as well as reverse-mode and haze-free characteristics. 96-100
