Bistable Polymer Stabilized Cholesteric Texture Light Shutter

We developed a bistable polymer stabilized cholesteric texture (PSCT) light shutter which can be switched between a transparent state and an opaque state by voltage pulses. The PSCT light shutter is switched to a transparent state by a low frequency voltage pulse and remains transparent after the pulse. It is switched to an opaque state by a high frequency voltage pulse and remains opaque after the pulse. It can be used for architectural and greenhouse windows and is very energy-efficient.
