| abstract |
The invention relates to a novel material intended for the production of an electro-optical closure device, characterized in that it consists of the combination of: at least one chiral ferroelectric smectic liquid crystal based on pyrimidines and / or thiadiazoles substituted with one or more groups selected from alkyl, alkyloxy, phenyl and oxirane groups; and a polymer resulting from the polymerization of 1,4-bis [4- (3-acryloyloxypropyloxy) -benzoyloxy] -2-methyl-benzene monomer. |
