The entire contents are incorporated by reference in this application.

技术领域technical field

本申请涉及电致变色器件技术领域，具体涉及一种基于聚合物分散液晶的电致变色装置、所述电致变色装置的制备方法，以及设有所述电致变色装置的电子设备。The present application relates to the technical field of electrochromic devices, in particular to an electrochromic device based on polymer-dispersed liquid crystals, a preparation method of the electrochromic device, and electronic equipment equipped with the electrochromic device.

背景技术Background technique

电致变色是指材料的光学属性(反射率、透射率或吸收率等)在外加电场作用下产生稳定、可逆的颜色变化的现象，在外观上表现为颜色和透明度的可逆变化。具有电致变色性能的材料称为电致变色材料，用电致变色材料做成的器件称为电致变色器件。现有技术中，通常会在聚合物分散液晶(polymer dispersed liquid crystal，PDLC)器件上设置电致变色(Electrochromism，EC)器件，以形成颜色和透明度的可逆变化的显示装置。现有的基于聚合物分散液晶的电致变色显示装置一般包括PDLC器件和EC器件，所述PDLC器件与所述EC器件相互独立地粘合于一体；即所述PDLC器件中包括一对电极，所述EC器件包括另一对电极，两对电极分别独立控制所述PDLC器件及EC器件，以实现透明与颜色的组合切换。Electrochromism refers to the phenomenon that the optical properties of materials (reflectivity, transmittance or absorptivity, etc.) produce stable and reversible color changes under the action of an external electric field, and the appearance is manifested as reversible changes in color and transparency. Materials with electrochromic properties are called electrochromic materials, and devices made of electrochromic materials are called electrochromic devices. In the prior art, an electrochromism (EC) device is usually provided on a polymer dispersed liquid crystal (PDLC) device to form a display device with reversible changes in color and transparency. Existing electrochromic display devices based on polymer-dispersed liquid crystal generally include a PDLC device and an EC device, and the PDLC device and the EC device are bonded together independently of each other; that is, the PDLC device includes a pair of electrodes, The EC device includes another pair of electrodes, and the two pairs of electrodes independently control the PDLC device and the EC device, so as to realize combined switching of transparency and color.

具体地，现有的电致变色显示装置的PDLC器件一般包括从下至上依次层叠设置第一透明非导电基底、第一透明导电层、设于所述第一透明导电层上的第一电极、聚合物液晶层(PDLC)、第二透明导电层及设于所述第二透明导电层与所述聚合物液晶层之间的第二电极；所述电致变色显示装置的EC器件一般包括从下至上依次层叠设置的第二透明非导电基底、第三透明的导电层、对电极、聚合物电解质(EC)、工作电极、第三透明的导电层及第三透明非导电基底，且所述第二透明非导电基底层叠于所述第二透明的导电层上。所述电致变色显示装置能实现透明与彩色散射状态之间的切换。然，现有的电致变色显示装置层叠的层数过多，电极数量较多，使得其整体厚度过大，限制了电致变色显示装置的运用场景。Specifically, the PDLC device of the existing electrochromic display device generally includes a first transparent non-conductive substrate, a first transparent conductive layer, a first electrode disposed on the first transparent conductive layer, A polymer liquid crystal layer (PDLC), a second transparent conductive layer, and a second electrode disposed between the second transparent conductive layer and the polymer liquid crystal layer; the EC device of the electrochromic display device generally includes The second transparent non-conductive substrate, the third transparent conductive layer, the counter electrode, the polymer electrolyte (EC), the working electrode, the third transparent conductive layer and the third transparent non-conductive substrate are stacked in order from bottom to top, and the The second transparent non-conductive substrate is laminated on the second transparent conductive layer. The electrochromic display device can realize switching between transparent and color scattering states. However, the existing electrochromic display device has too many stacked layers and a large number of electrodes, which makes its overall thickness too large, which limits the application scenarios of the electrochromic display device.

The present application provides an electrochromic device 100 based on polymer dispersed liquid crystal. The electrochromic device 100 includes a polymer dispersed liquid crystal device 20 and an electrochromic device 50. The electrochromic device 50 is laminated on the polymer dispersed liquid crystal device 20. Above, the polymer dispersed liquid crystal device 20 and the electrochromic device 50 share a common electrode 510 . That is, the common electrode 510 and the other electrode of the polymer dispersed liquid crystal device 20 can conduct to realize the haze switching of the polymer dispersed liquid crystal device 20; and the common electrode 510 and the other electrode of the electrochromic device 50 can realize conduction To realize the color change of the electrochromic device 50.

The bottom to top refers to the z-axis direction.

聚合物分散液晶层26由聚合物分散液晶制成，所谓聚合物分散液晶是液晶以微米量级的小微滴分散在有机固态聚合物基体内，由于由液晶分子构成的小微滴的光轴处于自由取向，其折射率与基体的折射率不匹配。当光通过基体时被微滴强烈散射而呈不透明的乳白状态或半透明状态。施加电场可调节液晶微滴的光轴取向，当两者折射率相匹配时，呈现透明态；除去电场，液晶微滴又恢复最初的散光状态，从而进行显示。Polymer dispersed liquid crystal layer 26 is made of polymer dispersed liquid crystal, and so-called polymer dispersed liquid crystal is that liquid crystal is dispersed in the organic solid polymer matrix with the small droplet of micron scale, because the optical axis of the small droplet that is made of liquid crystal molecule In free orientation, its refractive index does not match that of the matrix. When the light passes through the matrix, it is strongly scattered by the droplets and presents an opaque opalescent state or a translucent state. Applying an electric field can adjust the optical axis orientation of the liquid crystal droplet. When the refractive index of the two matches, it will be in a transparent state; remove the electric field, and the liquid crystal droplet will return to the original astigmatism state, thereby displaying.

具体地，所述电致变色材料可分为无机电致变色材料和有机电致变色材料，所述无机电致变色材料主要是过渡金属氧化物或水合物,CeO2-TiO2、NiOx、WO3、MnO2等；所述有机电致变色材料从结构上分主要有各种有机杂环化合物如联吡啶盐类、导电聚合物类、金属有机聚合物类和金属酞花菁类等。所述过渡金属氧化物中金属离子的电子结构不稳定，在一定条件下离子价态发生转变，形成混合价态离子共存的状态。随着离子价态的变化，颜色也改变。选择合适的过渡金属络合物配体利用电化学聚正当可以制成一系列聚合金属络合物，如在ITO玻璃上制成[Ru I(Vbpy)2-(Py)2]CI2膜。常用的络合物配体有Vpy、Vbpy、Vtpy、Py，中心金属离子有Fe、Ru、Os等。在无机变色材料中，阴材材料主要是VIB族金属氧化物,如WO3，MoO3等；阳极材料主要是第VIII族(Pt,Ir，Os，Pd,Ru,Rb等)金属氧化物和水合氧化物。有机电致变色材料包括但不限于聚噻吩类及其衍生物、紫罗精类、四硫富瓦烯、金属酞菁类化合物等。所述电致变色材料按照物质的状态可分为：薄膜型(固体)、析出型(固体和液体相互转化)和非析出型(溶液)。Specifically, the electrochromic materials can be divided into inorganic electrochromic materials and organic electrochromic materials, and the inorganic electrochromic materials are mainly transition metal oxides or hydrates, CeO2-TiO2, NiOx, WO3, MnO2 etc.; the organic electrochromic materials mainly include various organic heterocyclic compounds such as bipyridyl salts, conductive polymers, metal organic polymers and metal phthalocyanines in terms of structure. The electronic structure of metal ions in the transition metal oxide is unstable, and the valence state of the ions changes under certain conditions, forming a state where ions in mixed valence states coexist. As the valence state of the ions changes, so does the color. A series of polymeric metal complexes can be made by selecting appropriate transition metal complex ligands by electrochemical polymerization, such as [Ru I(Vbpy)2-(Py)2]CI2 film on ITO glass. Commonly used complex ligands include Vpy, Vbpy, Vtpy, and Py, and the central metal ions include Fe, Ru, and Os. Among the inorganic color-changing materials, the cathode materials are mainly VIB group metal oxides, such as WO3, MoO3, etc.; the anode materials are mainly group VIII (Pt, Ir, Os, Pd, Ru, Rb, etc.) metal oxides and hydrated oxides. thing. Organic electrochromic materials include, but are not limited to, polythiophenes and their derivatives, viologens, tetrathiafulvalenes, metal phthalocyanines, and the like. According to the state of matter, the electrochromic material can be divided into thin film type (solid), precipitation type (mutual transformation between solid and liquid) and non-precipitation type (solution).

酞花菁多分子膜(膜厚10-20nm，M＝Cu,Ni),在电压-2V-+2V之间能实现蓝绿黄红的变色效应。Phthalocyanine polymolecular film (film thickness 10-20nm, M=Cu, Ni), can realize the color changing effect of blue, green, yellow and red between the voltage of -2V-+2V.

所述电致变色材料的变色原理主要取决于材料的化学组成能带结构和氧化还特性。如，可通过离子、电子的注进和抽往，调制薄膜在紫外和可见光区的吸收特性或改变薄膜中载流子浓度和等离子振荡频率，实现以红外反射特性的调制。以WO3为例来具体说明：其中采用双重注进/抽出模型、价内迁移模型；如无定形WO3变色机理可用下式表示：xM++xe-+WO3＝MxWO3式中：M表示H+、Li+等。加电场时，电子e-和阳离子M+同时注进WO3膜原子晶格间的缺陷位置，形成钨青铜(MxWO3)，呈现蓝色。反方向加电场，电致变色层中电子e-和阳离子M+同时脱离，蓝色消失。在钨青铜中，电子在不同晶格位置A和B之间的移动可表示为：hγ+W5+(A)+W6+(B)＝W6+(A)+W5+(B)。另一采用极化子模型，电子注进晶体后与四周晶体相互作用而被域化在某个晶格位置，形成小极化子，破坏了平衡位形。小极化子在不同晶格位置跃迁时需要吸收光子；这种光吸收导致的极化子的跃变被称为Franck-Condon跃变。在跃变过程中，电子跃变能量全部转化为光子发射的能量。所产生的光吸收可表示为：a＝Ahωexp{(hω-ε-4U)/8Uhω}式中：hω是散射光子的能量；ε是初态与终态能级的能量差，U是活化能。小极化子模型不仅与WO3光吸收曲线很好的吻合，且还能对WO3蒸发过程中加进少数MoO3导致的光谱蓝移现象。The color changing principle of the electrochromic material mainly depends on the chemical composition, energy band structure and redox characteristics of the material. For example, through the injection and extraction of ions and electrons, the absorption characteristics of the film in the ultraviolet and visible light regions can be modulated or the carrier concentration and plasma oscillation frequency in the film can be changed to realize the modulation of infrared reflection characteristics. Take WO3 as an example to illustrate: the double injection/extraction model and intra-valence migration model are used; the discoloration mechanism of amorphous WO3 can be expressed by the following formula: xM++xe-+WO3=MxWO3 In the formula: M represents H+, Li+ Wait. When an electric field is applied, electrons e- and cations M+ are simultaneously injected into the defect positions between the atomic lattices of the WO3 film to form tungsten bronze (MxWO3), which appears blue. When an electric field is applied in the opposite direction, the electrons e- and cations M+ in the electrochromic layer are detached at the same time, and the blue color disappears. In tungsten bronze, the movement of electrons between different lattice positions A and B can be expressed as: hγ+W5+(A)+W6+(B)=W6+(A)+W5+(B). The other adopts the polaron model. After the electrons are injected into the crystal, they interact with the surrounding crystals and are localized in a certain lattice position, forming small polarons, which destroys the equilibrium configuration. Small polaritons need to absorb photons when transitioning between different lattice positions; the transition of polaritons caused by light absorption is called Franck-Condon transition. During the transition process, the electronic transition energy is completely converted into the energy emitted by photons. The resulting light absorption can be expressed as: a=Ahωexp{(hω-ε-4U)/8Uhω} where: hω is the energy of scattered photons; ε is the energy difference between the initial state and the final state energy level, and U is the activation energy . The small polaron model not only fits well with the light absorption curve of WO3, but also can account for the blue shift of the spectrum caused by the addition of a small amount of MoO3 during the evaporation of WO3.
