摘要：
A light controlling film is disclosed, comprising a polymerized polymer network varying spatially in a direction normal to the film surface, where the polymerized polymer network is a crosslinked high molecular weight polymeric material mixed with a low molecular weight nematic material exhibiting cholesteric liquid crystal (CLC) order, wherein an electric field impressed in the film controls the reflection bandwidth of circularly polarized light.
