Modulating Photochemical Properties to Enhance the Stability of Electronically Dimmable Eye Protection Devices

AbstractThe study evaluates compatibility of stabilizers with dye dopped liquid crystal (LC) scaffolds that are used in electronically dimmable materials. The photodegradation of the materials were investigated and suitable stabilizers were evaluated to slow the degradation process. Various types of benzotriazole based stabilizers were evaluated for stabilizing the liquid crystals Based on spin trapping experiments radical generated upon UV exposure is likely responsible for the degradation of the system. The radical generation is competitively inhibited by the addition of stabilizers.
