ABSTRACT:
A precursor for the preparation of a material with optical properties modifiable under the action of at least one external parameter, comprising a component A constituted by polymerizable monomers or oligomers, a component B comprising one or several liquid crystals with low molecular weights or polymers and having a type of molecular order that is nematic, cholesteric or smectic or having polymorphism, andat least one surface agent C whose molecules have an affinity both for component A and for component B, and comprising simultaneously one or several chemical groups that can attach chemically to the constituents of component A, and one or several chemical groups comprising a mesogenic portion compatible with the mesomorphic phase of component B, so as to control the interfacial properties between components A, and B during polymerization.
