摘　　要：液晶显示领域中的一个重要研究方向是液晶电光性能的改善。近年来,液晶-纳米科学见证了纳米掺杂增强液晶电光性质的范式转变。一方面,纳米颗粒具备特殊的理化性质能有效改善分散基质的性质;此外,纳米掺杂的液晶复合体系制备工艺简单、电光特性卓越,在显示领域占据重要地位。利用液晶与纳米颗粒间的不同相互作用,研究人员设计了一系列具有高稳定性、低成本、可调谐和可持续的电光器件。然而,纳米颗粒的掺杂有可能造成结构缺陷,不利于液晶的稳定。因此,纳米颗粒的选择是影响液晶电光性能的关键。本文概述了液晶-纳米复合体系的电光特性,着重讨论了纳米颗粒与液晶分子间可能存在的相互作用。同时,综述纳米颗粒掺杂液晶的研究现状,根据纳米颗粒类型总结了纳米掺杂对液晶电光性能的影响,并在此基础上,对未来液晶显示技术与纳米技术的结合进行了展望。An important research direction in the field of liquid crystal displays is the improvement of electro-optical properties of liquid crystals.In recent years,liquid crystal-nanoscience has witnessed a paradigm shift in the electro-optical properties of nano-doped enhanced liquid crystals.On the one hand,nanoparticles possess special physicochemical properties that can effectively improve the properties of the dispersed substrates.In addition,the nano-doped liquid crystal composite system occupies an important position in the display field because of its simple preparation process and excellent electro-optical properties.Using the different interactions between liquid crystals and nanoparticles,researchers have designed a series of electro-optical devices with high stability,low cost,tunable and sustainable.However,the doping of nanoparticles has the potential to cause structural defects that are detrimental to the stability of liquid crystals.Therefore,the selection of nanoparticles is crucial to the electro-optical performance of liquid crystals.This paper provides an overview of the electro-optical properties of liquid crystal-nanocomposite systems,focusing on the possible interactions between nanoparticles and liquid crystal molecules.Meanwhile,the current research status of nanoparticle-doped liquid crystals is reviewed,and the effect of nano-doping on the electro-optical properties of liquid crystals is summarized according to the nanoparticle types,and based on this,the future combination of liquid crystal display technology and nanotechnology is prospected.
