摘要:
The invention relates to a method for obtaining a material (10) comprising mesogenic compounds (101 ) forming a liquid crystal mix with a stabilized blue phase (100), comprising the following steps: a) preparing a chemical composition comprising a mesogenic system and a chemical photo-initiator system, the mesogenic system including - said mesogenic compounds forming the liquid crystal mix, - a chiral dopant adapted to induce said blue phase, and - a monomer mix comprising monomers adapted to polymerize, and the chemical photo-initiator system being adapted to trigger the polymerization of said monomers when illuminated by a light beam of visible wavelength; b) getting said liquid crystal mix to form said blue phase; c) after getting said liquid crystal mix into said blue phase, illuminating the chemical composition obtained in step a) with a light beam of visible wavelength in order to trigger the polymerization of said monomers; d) obtaining said material comprising said liquid crystal mix in the blue phase stabilized by the polymerized monomers.
