Abstract
Disclosed is a novel type of composite electro-optical material based on liquid crystal dispersed in a polymer with reactive functional groups (Y). The originality of this material lies in the chemical modification of the interface between the polymer and the liquid crystal leading to the formation of a composite material comprising a porous network of polymer and liquid crystal molecules in the pores of the network. The polymer possesses reactive functional groups (Y) and functional groups (X) at the interface between the polymer and the liquid crystal. The totality constituted by the functional groups (Y) and the functional groups (X) enables the optimizing of the electro-optical performance characteristics obtained from this type of material. Also disclosed is a method to obtain this composite material as well as a device comprising a material such as this.
