Various non-limiting embodiments disclosed herein provide phase-separating polymer systems including a cured polymeric liquid crystal matrix phase and a guest phase including at least one photoactive material where the guest phase separates from the matrix phase during the curing process. Optical elements, including ophthalmic elements and other articles of manufacture including the phase-separating polymer systems are also disclosed. Methods of forming a liquid crystal phase-separating photoactive polymer system are also described.
La présente invention porte selon divers modes de réalisation non limitatifs sur des systèmes de polymères à séparation de phases comprenant une phase matrice cristalline liquide polymère durcie et une phase invitée comprenant au moins une matière photoactive, la phase invitée se séparant de la phase matrice pendant le procédé de durcissement. L'invention porte également sur des éléments optiques, dont des éléments ophtalmiques et autres articles manufacturés, comprenant les systèmes de polymères à séparation de phases. L'invention porte également sur des procédés de formation d'un système de polymères photoactif à séparation de phase cristalline liquide.
