Abstract
A method for obtaining a material containing mesogenic compounds forming a liquid crystal mix with a stabilized blue phase. The method includes the steps of a) inducing the liquid crystal mix, contained in a chemical composition, to form the blue phase, then b) illuminating the chemical composition with a light beam of visible wavelength in order to trigger the polymerization of monomers contained in the chemical composition, to obtain the material comprising the liquid crystal mix in the blue phase stabilized by the polymerized monomers. The chemical composition contains a mesogenic system and a chemical photo-initiator system adapted to trigger the polymerization of the monomers when illuminated by the light beam of visible wavelength, in which the mesogenic system includes the mesogenic compounds forming the liquid crystal mix, a chiral dopant adapted to induce the blue phase, and a monomer mix comprising the monomers adapted to polymerize.
