Title (EN) LIGHT MODULATING MATERIAL COMPRISING POLYMER DISPERSED LIQUID CRYSTALS
(FR) MATERIAU DE MODULATION DE LUMIERE CONTENANT DES CRISTAUX LIQUIDES DISPERSES DANS UN POLYMERE
Abstract:
(EN) A light modulating material is disclosed, comprising a solid, light transmissive, polymeric matrix having dispersed within said matrix droplets of a liquid crystalline composition, wherein said composition is a mixture of at least 2 compounds, at least one of said compounds having general formula (I), where n is 1 or 2, the fluorine substituent(s) may be in any of the available substitution positions and R1 is C1-12 alkynyl, hydrogen, R, RO or RCO where R is alkyl or perfluoroalkyl and at least one other of said compounds having general formula (II), where m is 0 or 1 and R2 is hydrogen or C1-12 alkyl or alkoxy.
(FR) On décrit un matériau de modulation de lumière comportant une matrice polymère solide et translucide, dans laquelle sont dispersées des gouttelettes d'un liquide ayant une composition cristalline. Ladite composition est constituée par un mélange d'au moins deux composés, dont au moins un posséde la formule générale (I), où n est 1 ou 2, le(s) substituant(s) du fluor peuvent se trouver dans l'une quelconque des positions de substitutions disponibles, et R1 est C1-12 alkynyle, hydrogène, R, RO ou RCO où R est alkyle ou perfluoroalkyle et au moins un autre desdits composés ayant la formule générale (II), où m est 0 ou 1 et R2 est hydrogène ou C1-12 alkyle ou alkoxy.
