摘要： A device having scattering which can be varied by liquid crystals includes a stack with a first electrode, an electroactive layer with the liquid crystals being stabilized by the polymeric network, a second electrode. The material exhibits, starting from a temperature referred to as T1, a mesophase referred to as P. At a temperature T′ greater than or equal to T1, the stack is capable of exhibiting at least three variable scattering states, which are stable and reversible, in the visible region.
