P-132: Influence of Polymerization Conditions on Response Time of Encapsulated Cholesteric LCs

This paper study the influence of surface properties of encapsulated CLC on response time and reflectance via polymerization induced phase separation. The cured polymer layer, which is composed of the mixture of EMA and TRI, adhere to the inside of the non-treated glass substrate and change the surface properties to vertical alignments. Different boundary conditions caused by various UV curing intensity and cell gap lead to different electro-optical properties for CLC display. With a proper boundary structure, the transition time from homeotropic to planar of CLC can be reduced obviously with slightly reduced reflectance.
