Polymer Dispersed Liquid Crystals for Electronic Applications
The electrooptic characteristics of liquid crystal-polymer composites (PDLC, PNLC, NCAP...) are strongly dependent on surface interactions between polymer and liquid crystal molecules. In order to clarify this dependence, we have investigated the chemical modification of the surface of the polymer, without affecting its bulk properties. We show that it is possible to greatly modify the electrooptic performances of composite cells, and thus to optimise them for an application in visualisation.
