Description

导电基材及电致变色器件
本申请要求在2020年11月3日提交中国专利局、申请号为202011209955.X、名称为“一种导电基材及电致变色器件”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及电致变色技术领域，例如涉及一种导电基材及电致变色器件。
背景技术
电致变色是材料的光学属性在外加电场的作用下发生稳定且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，在光学器件、灯具、玻璃制品以及装饰品等方面都有着非常广泛的应用。
相关技术中，电致变色器件的布线均设置在器件的边缘，因此，尤其是对于大面积电致变色器件，由于电致变色器件的透明导电层有一定的方阻，因此施加在边缘的电压在传导到器件的中心时，会小于施加的电压值，从而很容易形成晕光现象，即器件四周已经变色而中间还没有变色或变色缓慢。
针对这一情况，目前通常是通过优化变色逻辑来避免，如通过减小施加在器件上的电压或电流，或通过脉冲充电的方式，来降低器件的变色速度，从而达到视觉上的均匀变色。但是这种方式牺牲了变色速度，尤其当电致变色器件的面积进一步增大时，例如应用在建筑的顶窗等环境中，变色的过程会非常耗费时间，变色时长可能会增加至几十分钟，从而无法及时的实现变色。

本申请实施例提供了一种导电基材，该导电基材包括：基底层、导电层以及布线层；其中，导电层设置在基底层上；布线层设置在导电层上，布线层包括沿第一方向设置的第一导电线路以及沿第二方向设置的第二导电线路，如图1所示，第一导电线路21从导电层1的边缘向内延伸，第二导电线路22设置在导电层1的边缘，第一导电线路21与第二导电线路22电连接。
其中，基底层可以是一种透明基底，且为光学级透明材料，例如可以是柔性基底材料，包括聚酯薄膜(Polyester Film，PET)、环烯烃共聚物或三醋酸纤维素等。导电层可以选用氧化铟锡(indium-tin oxide，ITO)、氧化锌铝(aluminum zinc oxide，AZO)、氟掺杂氧化锡(fluorine doped tin oxide，FTO)、银纳米线、石墨烯、碳纳米管、金属网格或银纳米颗粒等导电材料。第一导电线路和第二导电线路可以选用导电银浆、导电铜浆、导电碳浆、纳米银导电油墨、铜箔、铜丝或导电胶膜等导电材料中任意一种或至少两种的组合；也可直接采用与导电层相同的材料，且导电带处的材料厚度更大，电阻更小，从而在保证导电功能的同时，由于材料本身是透明的，可以增加产品视觉上的一致性。在使用本实施例所提供的导电基材的过程中，可以在第二导电线路上连接引出电极，再由第二导电线路将外部电场传导至第一导电线路，从而方便的通过外部电源为导电基材供电。
如图1所示，第一导电线路21的一端可以连接在第二导电线路22上，并从第二导电线路22开始向内延伸，从而使得布线层的边缘较为整齐，在应用时 还可以减少遮蔽层的使用。第二导电线路22与导电层1的边缘之间可以呈任意角度，第一导电线路21与第二导电线路22之间可以呈任意角度。例如，第二导电线路22与导电层1的边缘平行，使得正反形状相同，从而在应用到电致变色器件中时，上下两层导电基材可以使用同一母版进行加工。此时第二导电线路22的长度应小于导电层1边缘的长度，例如可以是导电层1边缘的长度减2毫米。由于第二导电线路22位于导电层1的边缘，因此在应用时不容易影响到产品整体的美观性，因此其宽度相对于第一导电线路21可以略宽，同时导电线路的宽度越宽电阻越小，压降越小，从而减小压降对变色均匀性的影响。第二导电线路22的宽度可以是0.5-50毫米，例如可以为5毫米。相应的，第一导电线路21的宽度可以是小于20毫米，例如可以为小于0.5毫米，从而避免过于明显，当第一导电线路21的宽度大于5毫米时，可以设置对应的遮挡层进行遮挡，从而提高产品的美观性。
第二导电线路22可以是连续的或者不连续的，当为不连续时，可以在应用时通过使用导电带连接相邻的两段第二导电线路22以实现布线层的电连通。其中，导电带可以是利用导电银浆、导电铜浆、导电碳浆、纳米银导电油墨、铜箔、铜丝或导电胶膜等导电材料中任意一种或至少两种的组合事先制成的胶带状导电线路；也可直接采用与导电层相同的材料，且导电带处的材料厚度更大，电阻更小，从而在保证导电功能的同时，由于材料本身是透明的，可以增加产品视觉上的一致性。
如图1所示，第一导电线路21包括多条间隔设置的导电线路，第二导电线路22设置在第一导电线路21的一侧。例如，第一导电线路21中的导电线路互相间隔且第二导电线路22设置在第一导电线路21的一侧，可以减少在应用到电致变色器件时两层导电基材之间的重叠，从而避免电致变色器件在重叠处首先进行反应而造成的变色不均匀的情况，同时只需要在导电层1的一侧引出电极供电即可。
如图1所示，第一导电线路21远离第二导电线路22的一端与导电层1远离第二导电线路22的边缘之间的距离大于第一导电线路21靠近第二导电线路22的一端与导电层1靠近第二导电线路22的边缘之间的距离，从而进一步减少在应用到电致变色器件时两层导电基材之间的重叠。
第一导电线路与第二导电线路的形状可以根据导电基材整体的形状进行设置，例如，第二导电线路的形状可以与导电基材的边缘形状一致。如图1所示， 导电层1可以为方形，第一方向沿导电层1的一侧边延伸，第二方向沿导电层1的与一侧边相邻的另一侧边延伸，即第二导电线路22沿导电层1一侧边的边缘延伸，而第一导电线路21从该边缘沿相邻的另一侧边的方向向内部延伸。如图1-3所示，第一导电线路21为直线(如图1所示)、弯折线(如图2所示)或曲线(如图3所示)中的任意一种，第二导电线路22为直线(如图1所示)、直线(如图2所示)或曲线(如图3所示)中的任意一种。
如图4所示，第一导电线路21为多条平行设置的直线，第二导电线路22为直线，第一导电线路21与第二导电线路22垂直设置。由于导电线路本身也会存在一定的压降，因此导电线路越短则压降越小，更有利于实现缩小内外的电势差，而通过将第一导电线路21与第二导电线路22设置为直线且相互垂直，则可以减小导电线路的长度，从而减小在导电线路上消耗的压降。
如图5所示，导电层1还可以为圆形，第二方向沿导电层1的周边延伸，第一方向沿导电层1的外围向中心螺旋延伸。第一导电线路21为螺旋线，第二导电线路22为圆弧。
本申请实施例所提供的导电基材，通过在导电层上设置布线层，且布线层包括从导电层边缘向内延伸的第一导电线路以及设置在导电层边缘的第二导电线路，缩小了导电基材在通电时边缘与中心的电势差，从而在将该导电基材应用到电致变色器件中时，减弱了晕光现象，实现了更均匀的变色过程，同时，尤其针对面积较大的电致变色器件，还保证了较快的变色速度。
本申请实施例提供了一种导电基材。本实施例的技术方案在上述实施例技术方案的基础上进一步细化，如图6所示，布线层还包括：引出结构23，引出结构23与第二导电线路22电连接。引出结构23的材料可以与第二导电线路22相同，形状可以是L形、I形、T型等，连接在第二导电线路22上，或是第二导电线路22的结构延伸，可以在应用到电致变色器件时，用于替代第二导电线路22与引出电极进行连接，从而避免了对第二导电线路22的破坏，也降低了焊接的难度。例如，引出结构23为一个，可以连接在第二导电线路22的一端或中心。如图7所示，第一导电线路21中相邻的导电线路之间的距离沿电压减小的方向呈递减变化。由于此时第二导电线路22上也存在一定的压降，使得远离引出结构23的一端的电压小于靠近引出结构23的一端的电压，因此可以通过缩短相邻导电线路之间的距离，来提高远离引出结构23的一端的变色速度， 进一步提高整体变色的一致性。其中，相邻导电线路之间的距离可以呈等差序列分布。
如图8所示，引出结构包括：中间引出结构231和端点引出结构232，中间引出结构231设置于第一导电线路21中相邻的导电线路与第二导电线路22的两个交点的中点，端点引出结构232设置于第二导电线路22的端点。当所需的导电基材的尺寸较大时，第二导电线路22上的压降可能较大，对变色过程的影响可能比较明显，则可以通过均匀的设置多个引出结构，并分别对导电基材进行供电，从而减小第二导电线路22上电压的损耗。特别的，由于制作工艺的影响，很难生产连续一定长度(如一米)以上的第二导电线路22，当所需的导电基材的尺寸足够大时，第二导电线路22可能是非连续的，此时相邻的两段第二导电线路22中的相邻两个端点处可以分别连接一个端点引出结构232，并且可以将两个端点引出结构232共同组成一个引出结构后再与引出电极连接，也可以分别由两个端点引出结构232单独成为一个引出结构与引出电极连接，从而与外部的供电电路连接。如图8所示，第一导电线路21中相邻的导电线路之间的距离相同。由于在第一导电线路21中每两条相邻的导电线路与第二导电线路22的两个交点的中点以及第二导电线路22的端点均设置了引出结构，此时再将第一导电线路21中相邻的导电线路之间的距离设置为相同，则可以使得导电层1上的电场分布更加均匀。
本申请实施例所提供的导电基材，通过在布线层上设置用于替代第二导电线路与引出电极连接的引出结构，并与第二导电线路连接，避免了在应用到电致变色器件时，对第二导电线路造成的破坏，从而保证了导电层上所需的电场分布，同时也降低了焊接引出电极的难度。
本申请实施例提供了一种导电基材。本实施例的技术方案在上述实施例技术方案的基础上进一步细化，如图9所示，第一导电线路21的末端包括对称设置的分叉结构211。由于在应用到电致变色器件上时，第一导电线路21的末端通常不会以矩形向外扩散变色的区域，而是以类似圆弧状扩散，则即使在其他方面上已经完成细化，在矩形与圆弧形的非重叠部分也会存在一个始终变色较慢的区域，因此，通过将第一导电线路21的末端设置为对称的分叉结构211，可以有效减小变色较慢的区域，从而进一步提高整体变色的均匀性。例如，如图9所示，在方形的导电层1中，第二导电线路22为直线，并与导电层1的边 缘平行，第一导电线路21为多条平行设置且间隔相同的直线，并与第二导电线路22垂直设置，然后在第一导电线路21的末端设置对称的分叉结构，则可以尽可能的提高整体变色的均匀性。
本申请实施例所提供的导电基材，通过将第一导电线路的末端设置为对称的分叉结构，减小了应用该导电基材的电致变色器件上变色较慢的区域，进一步提高了变色过程的均匀性。
本申请实施例提供了一种导电基材。本实施例的技术方案在上述实施例技术方案的基础上进一步细化，如图10所示，导电基材还包括：对位孔3，对位孔3设置在基底层和导电层1的边缘区域。对位孔3的数量为至少两个，贯穿导电基材，并可以设置在导电层1的一侧边缘区域或多侧边缘区域，以在应用到电致变色器件时，能够更好的保证上下两层导电基材之间按需对位的精确性，且通过设置在边缘，也不会对变色过程造成影响。例如，如图10所示，对位孔3设置在导电层1的上下两侧边缘区域，从而使得对位更加方便准确。
本申请实施例所提供的导电基材，通过在基底层和导电层的边缘区域设置对位孔，实现了电致变色器件中上下两层导电基材之间的精确对位，从而满足上下两层导电基材中第一导电线路之间所需的位置关系，以实现对变色过程的精准控制。
本申请实施例提供了一种导电基材。本实施例的技术方案在上述实施例技术方案的基础上进一步细化，如图11-13所示，布线层2设置在导电层1远离基底层4一侧的表面(如图11所示)、嵌入导电层1(如图12所示)或者嵌入导电层1和基底层4(如图13所示)。图中所示的布线层2仅仅是针对与基底层4和/或导电层1之间的位置关系，并非对布线层2具体形状的限制。布线层2与基底层4之间的位置关系可以是任意的，只需要保证布线层2与导电层1相接触即可，还可以包括布线层2的一部分在导电层1的表面而另一部分嵌入导电层1。其中，布线层2的高度可以根据位置进行设置，当布线层2设置在导电层1远离基底层4一侧的表面时，布线层2的高度应当小于应用的电致变色器件中上下两层导电层之间的距离，当布线层2嵌入导电层1时，布线层2的高度可以小于或等于导电层1的高度，并在布线层2的高度小于导电层1的高度时可以设置在导电层1中的任意位置，如靠近导电层1的边缘或中心等等，当布线 层2嵌入导电层1和基底层4时，布线层2的高度可以小于或等于导电层1与基底层4的厚度之和。同时，布线层2的高度还可以根据所选取的导电材料进行设置，不同的导电材料的导电率可能不同，因此可以根据导电材料调整布线层2的高度来保证一个较好的导电性。示例性的，当导电材料选用丝印银浆时，布线层2的高度可以是3-5微米。
在上述技术方案的基础上，如图14所示，布线层还包括：包裹第一导电线路和第二导电线路的绝缘层和/或保护层24。当第一导电线路和第二导电线路的一部分裸露在外时，则可以通过在第一导电线路和第二导电线路的表面设置绝缘层来保证其与电致变色器件中的另一导电层之间的电绝缘，也可以通过在第一导电线路和第二导电线路的表面设置保护层来防止环境对其中导电线路的腐蚀。
本申请实施例所提供的导电基材，提供了布线层多种位置的设置方式，均可以实现所需的功能，同时还可以通过设置绝缘层和/或保护层来实现对布线层中导电线路相对另一导电基材的绝缘以及对环境腐蚀的保护。
图15为本申请实施例提供的电致变色器件的结构示意图。如图5所示，该电致变色器件包括依次叠加设置的：第一导电基材5、电致变色层6以及第二导电基材7，第一导电基材5的基底层51远离电致变色层6设置，第二导电基材7的基底层71远离电致变色层6设置；其中，第一导电基材5和第二导电基材7为上述实施例中的任一导电基材，具备该导电基材相应的功能结构和有益效果。
第一导电基材5和第二导电基材7可以选用布线层相同或相对应的导电基材。电致变色层6可以包括电致变色材料层、离子传导层和离子存储层，通过对第一导电基材5的导电层52和第二导电基材7的导电层72之间施加电压，即可使得离子在电致变色材料层和离子存储层之间移动，进而使得电致变色组件的透过率发生变化。
例如，如图16所示，第一导电基材的第一导电线路531与第二导电基材的第一导电线路731交错平行设置。第一导电基材的第一导电线路531中的导电线路之间的间隔以及第二导电基材的第一导电线路731之间的间隔可以根据引出结构的布置情况进行设置，具体内容可以参考上述实施例中的描述，在此将不再累述。
例如，如图17所示，第一导电基材的第二导电线路532设置于沿叠加方向 相对第二导电基材的第二导电线路732的对向侧。图17中以第一导电基材的第一导电线路中的导电线路之间的间隔相同以及第二导电基材的第一导电线路中的导电线路之间的间隔相同为例进行示出，可以尤其适用于面积较大的电致变色器件，通过将第一导电基材的第二导电线路532设置于沿叠加方向相对第二导电基材的第二导电线路732的对向侧，可以避免沿叠加方向上的重叠，从而避免电致变色器件在重叠处首先进行反应而造成变色不均匀的情况。
例如，如图18所示，第一导电基材的第一导电线路531中相邻的导电线路之间的距离相同，且沿叠加方向，第二导电基材的第一导电线路731设置于相邻的两条第一导电基材的第一导电线路531的中间位置，第一导电基材的第一导电线路531远离第一导电基材的第二导电线路532一端与第二导电基材的第二导电线路732之间的距离为第一距离，第一导电基材的第一导电线路531与相邻的第二导电基材的第一导电线路731之间的距离为第二距离，第一距离小于或等于第二距离。由于第一距离靠近电致变色器件的边缘，因此若第一距离较小，则仅存在一小部分区域的变色速度较快，而在电致变色器件的使用中，边缘上通常会使用遮挡层来提高美观性，此时也就不易察觉整体变色的差异，同时电致变色器件内部的导电线路可以保证内部的变色过程以一个较快的速度进行，并且多个区域的变色速度几乎一致，因此在变色均匀性上影响不大。当第一距离大于第二距离时，则第一距离更加靠近电致变色器件的中心，则可能会对变色均匀性造成较明显的影响。例如，第一距离与第二距离相等，则可以保证图18中两个虚线框区域基本同时完成变色，从而使得电致变色器件整体的变色过程都非常均匀。在此基础上，还可以分别在第一导电基材的第一导电线路531以及第二导电基材的第一导电线路731的末端对称设置分叉结构，以进一步提高电致变色器件整体变色的均匀性，具体内容可以参考上述实施例中的描述，在此将不再累述。
本申请实施例所提供的电致变色器件，有效的减弱了电致变色器件上的晕光现象，实现了较为均匀的变色过程，同时，尤其针对面积较大的电致变色器件，还保证了较快的变色速度。
