Polymer-stabilized liquid crystals (PSLCs) are multi-functional materials consisting of polymer networks in a continuous phase of liquid crystals (LCs), of which polymer networks provide anchoring energy to align the LCs. A number of improvements are detailed, including polymer-stabilized nematic liquid crystals (PSNLCs), polymer-stabilized cholesteric liquid crystals (PSCLCs), polymer-stabilized blue phase liquid crystals (PSBPLCs), polymer-stabilized smectic liquid crystals (PSSLCs), polymer-stabilized ferroelectric liquid crystals (PSFLCs), and polymer-stabilized antiferroelectric liquid crystals (PSAFLCs) in this review. Polymer stabilization has achieved multiple functionalities for LCs; in smart windows, a sufficiently strong electric field allows the LCs to reorient and enables switching from a scattering (transparent) state to a transparent (scattering) state. For broadband reflectors, the reflection bandwidth of LCs is manually tuned by electric fields, light, magnetic fields, or temperature. PSBPLCs open a new way for next-generation displays, spatial light modulators, sensors, lasers, lenses, and photonics applications. Polymer networks in PSFLCs or PSAFLCs enhance their grayscale memories utilized in flexible displays and energy-saving smart cards. At the end, the remaining challenges and research opportunities of PSLCs are discussed.
聚合物稳定液晶（PSLCs）是一种多功能材料，由处于液晶（LCs）连续相中的聚合物网络组成，其中聚合物网络提供锚定能以使液晶排列。本文详细介绍了一些改进，包括聚合物稳定向列相液晶（PSNLCs）、聚合物稳定胆甾相液晶（PSCLCs）、聚合物稳定蓝相液晶（PSBPLCs）、聚合物稳定近晶相液晶（PSSLCs）、聚合物稳定铁电液晶（PSFLCs）和聚合物稳定反铁电液晶（PSAFLCs）。聚合物稳定化已为液晶实现了多种功能；在智能窗中，足够强的电场可使液晶重新取向，并实现从散射（透明）状态到透明（散射）状态的切换。对于宽带反射器，液晶的反射带宽可通过电场、光、磁场或温度进行人工调节。聚合物稳定蓝相液晶为下一代显示器、空间光调制器、传感器、激光器、透镜及光子学应用开辟了一条新途径。聚合物稳定铁电液晶或聚合物稳定反铁电液晶中的聚合物网络增强了它们在柔性显示器和节能智能卡中所利用的灰度记忆。最后，讨论了聚合物稳定液晶的剩余挑战和研究机遇。
