Description

光致变色混合物、光致变色器的制作方法及应用
技术领域
本发明属于头戴显示装置技术领域，具体来讲，涉及一种光致变色混合物、基于该光致变色混合物制备光致变色器的方法、以及该方法获得的光致变色器在光透过式头戴显示装置中的应用。
背景技术
不同于VR头盔将人的视线与现实世界完全隔离，AR眼镜的显示效果会受到现实世界中光线的影响，因此AR眼镜对于亮度的要求就要比VR头盔高的多。在室外环境中，AR在光穿透式头戴显示应用中会遇到在强光下成像和可见度变低下降的问题。在这个情况下，光透过式头戴显示装置需要具有强的自发光亮度或通过阻挡外光的方式来增加对比度；但强的自发光需要高电量消耗，由此会减低器件寿命，因此在室外环境中通过适当的阻挡外部光透过光穿透式头戴显示装置，以改变对比度是很有必要的。
一般来讲，当用户在室外时，太阳光强度比AR眼镜内部的显示光高几个数量级，因此使该AR眼镜中的镜片具有自动调光的技术就显得非常必要。
发明内容
为解决上述现有技术存在的问题，本发明提供了一种光致变色混合物，该光致变色混合物能够用于制作应用于光透过式头戴显示装置的光致变色器，从而克服了光透过式头戴显示装置在强光照射下对比度下降、显示效果减低的问题。
为了达到上述发明目的，本发明采用了如下的技术方案：
一种光致变色混合物，包括以溶剂溶解混合均匀的光致变色材料和热固化透明高分子材料。
进一步地，在所述光致变色混合物中，所述光致变色材料与所述热固化透明高分子材料的质量之比为1:20～1:5。
进一步地，所述光致变色材料在紫外光照射下发生顺反异构体转变、或开环反应、或成环反应，且所述所述光致变色材料在室光照射下发生顺反异构体转变的逆反应、或开环反应的逆反应、或成环反应的逆反应。
进一步地，所述光致变色材料选自偶氮苯类衍生物、螺吡喃类衍生物、双噻吩烯基类衍生物中的至少一种。
进一步地，所述光致变色材料具有如式1-1～1-3任一所示的结构：
其中，在式1-1中，R1为官能团或聚合物支链；R2、R3均为不含H的官能团；在式1-2中，R4、R5均为官能团或聚合物支链；在式1-3中，R6为官能团或聚合物支链。
进一步地，在所述式1-1中，R2、R3均选自-F、-Cl、-Br、-I、-NO2中的任意一种。
进一步地，所述热固化透明高分子材料选自环氧树脂、聚硅氮烷、聚酰亚胺中的任意一种；所述溶剂为芳香烃溶剂。
本发明的另一目的还在于提供一种光致变色器的制作方法，包括步骤：
S1、将上述的光致变色混合物作为涂液，涂覆于玻璃表面上；
S2、干燥涂覆有所述光致变色混合物的玻璃，所述光致变色混合物中的光致变色材料和热固化透明高分子材料固化形成光致变色膜，获得光致变色器。
进一步地，在所述步骤S2中，干燥温度为100℃～150℃，干燥时间为5min～20min。
本发明的另一目的还在于提供一种光透过式头戴显示装置，至少包括如上制作方法获得的光致变色器。
本发明通过配制一种光致变色混合物，继而以该光致变色混合物为涂液制作成光致变色器，将该光致变色器应用于光透过式头戴显示装置中，利用其中光致变色材料在紫外光和室光下结构的改变导致其吸收光谱发生明显的变化而发生颜色变化这一特性，其一可以提高头戴显示装置在强光下的对比度，提高显示效果，其二可以减少自然环境紫外光对人眼的伤害，其三可以在同等光学需求下使得光透过式头戴显示装置中的自主发光器件所需能耗相应降低，更加节能环保；同时，根据本发明的光致变色器的通用性强，也可适用于其他头戴显示装置的对比度改善中。

实施例1
本实施例提供了一种光致变色混合物，其包括以溶剂溶解混合均匀的光致变色材料和热固化透明高分子材料。
具体来讲，在该光致变色混合物中，光致变色材料与热固化透明高分子材料的质量之比为1:20～1:5；溶剂的作用仅用于溶解光致变色材料和热固化透明高分子材料，因此溶剂的用量无需特别限定，优选为芳香烃溶剂即可。
光致变色现象是该光致变色材料的必不可少的特性，光致变色现象是指一个化合物在受到一定波长的光辐照下可进行特定的化学反应获得产物，由于结构的改变导致其吸收光谱发生明显的变化发生颜色变化，而在另一波长的光照射下或热的作用下，又能恢复到原来的形式的现象。
更为具体地，本实施例中的光致变色材料是一种能够在紫外光照射下发生顺反异构体转变、或开环反应、或成环反应，且在室光照射下又能上述反应对应的逆反应的物质。
以偶氮苯为例，偶氮苯化合物含有共轭π体系，在紫外光至可见红光波段具有很强的吸收。偶氮苯化合物在紫外光区域显示一组很强的π-π*跃迁，而在可见光区域显示一组较弱的n-π*跃迁。对大多数偶氮苯化合物而言，反式异构体(可见光透过率高)在强光照射条件下，可以高效的转变为顺式异构体(可见光透过率低)，而在加热或室光条件下，顺势异构体又可以完全可逆的转变为反式异构体。
优选地，光致变色材料选自偶氮苯类衍生物、螺吡喃类衍生物、双噻吩烯基类衍生物中的至少一种，如可以是具有如下式1-1～1-3任一所示的结构：
其中，在式1-1中，R1为官能团或聚合物支链；R2、R3均为不含H的官能团，优选为-F、-Cl、-Br、-I、-NO2中的任意一种，这是由于-OH、-NH2、-HSO3等含有H的官能团极易产生氢键作用，使得偶氮苯类衍生物的异构转变困难，将会大大降低顺反异构转变的速率。
在式1-2中，R4、R5均为官能团或聚合物支链；在式1-3中，R6为官能团或聚合物支链。
值得说明的是，上述官能团是指羟基、羧基、氨基、羰基等任意有机化学中一般指代的官能团，而聚合物支链是指上述式1-1～1-3所示的结构整体以支链的形式连接在某聚合物上。
进一步地，在该热固化透明高分子材料的作用在于在使用过程中固化成膜，因此优选自环氧树脂、聚硅氮烷、聚酰亚胺中的任意一种，当然，其他能够与光致变色材料良好互溶且能通过热固化成膜的透明高分子材料均可，此处不作具体限定。
以下就上述式1-1～1-3所示的三种光致变色材料的具体光致变色过程进行详细的描述。
如上式1-1所示的偶氮苯类衍生物，当其受到强紫外光(一般指波长小于360nm的紫外光)照射时，其会发生如下反应式1的顺反异构转变，生成式2-1所示的物质，从而其吸收光谱发生明显的变化而发生颜色变化；而转变后的如式2-1所示的结构在受到室光的照射时，又发生逆反应而转变成式1-1所示的结构，从而体现光致变色性能。
如上式1-2所示的螺吡喃类衍生物，当其受到强紫外光(一般指波长小于360nm的紫外光)照射时，其会发生如下反应式2的开环反应，生成式2-2所示的物质，从而其吸收光谱发生明显的变化而发生颜色变化；而转变后的如式2-2所示的结构在受到室光的照射时，又发生逆反应而转变成式1-2所示的结构，从而体现光致变色性能。
如上式1-3所示的双噻吩烯基类衍生物，当其受到强紫外光(一般指波长小于360nm的紫外光)照射时，其会发生如下反应式3的成环反应，生成式2-3所示的物质，从而其吸收光谱发生明显的变化而发生颜色变化；而转变后的如式2-3所示的结构在受到室光的照射时，又发生逆反应而转变成式1-3所示的结构，从而体现光致变色性能。
实施例2
本实施例提供一种基于上述实施例1中的光致变色混合物来制作光致变色器的方法，该光致变色器的制作方法包括下述步骤：
在步骤S1中，将实施例1中的的光致变色混合物作为涂液，涂覆于玻璃表面上。
一般来讲，待涂覆的玻璃需提前清洗干净并真空干燥处理。
在步骤S2中，干燥涂覆有光致变色混合物的玻璃，光致变色混合物中的光致变色材料和热固化透明高分子材料固化形成光致变色膜，获得光致变色器。
具体来讲，一般干燥温度控制为100℃～150℃、干燥时间控制为5min～20min即可。
优选地，在真空条件下进行干燥。
值得说明的是，获得的光致变色器中的光致变色膜的厚度具体根据需求来确定，此处不作具体限定，一般而言，厚度越大，则获得的光致变色器在使用过程中越不易受到环境光的影响；同时，若涂覆一次未达到目标厚度，则通过多次涂覆与干燥来获得理想厚度即可。
实施例3
在该实施例中，基于上述实施例2制作获得的光致变色器，提供了一种光透过式头戴显示装置，如图1所示，该光透过式头戴显示装置至少包括偏振光分光器11、设置在偏振光分光器11相对两侧的反光镜12和自发光器13、以及设置在偏振光分光器11的远离使用者眼睛一侧的光致变色器14；在图1中，带箭头的直线表示环境光的方向，而带箭头的虚线表示由自发光器13出射及由反光镜12反射的自发光的方向。
如此，当使用该光透过式头戴显示装置时，朝向外侧的光致变色器14即可大幅降低环境光的影响。
由此，具有上述光致变色器14的光透过式头戴显示装置其一可以提高在强光下的对比度，提高显示效果，其二可以减少自然环境紫外光对人眼的伤害，其三可以在同等光学需求下降低其中的自发光器13所需的能耗，更加节能环保；同时，本发明中的光致变色器不仅限于本实施例中的光透过式头戴显示装置，其通用性强，也可适用于其他头戴显示装置的对比度改善中。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
