Description
技术领域
本发明涉及建筑家居生活领域,尤其是涉及一种多稳态电响应智能窗及其制备方法。
背景技术
基于液晶材料的隐私保护智能窗可以根据人们的需要调节光的反射,散射和透射,从而平衡保护隐私和采光的需求,且可以通过掺杂染料等物质获得较丰富的色彩,以染料掺杂彩色智能窗为例,通过外接电压控制液晶分子的转动来带动染料分子的重新排列,实现对阳光的透过、散射或吸收,来满足人们的需求。
但染料分子在紫外光的作用下会产生褪色等变化,影响染料掺杂智能窗的稳定性;由于染料分子无法达到理想的取向状态,因此染料掺杂智能窗在透明状态时染料分子仍然存在吸收行为,使智能窗无法达到无色透明的状态。
发明内容
针对现有技术的不足,本发明所要解决的技术问题是提供一种多稳态电响应智能窗及其制备方法。
本发明所采取的技术方案是:
本发明提供了一种多稳态电响应智能窗,包括依次层叠设置的透光导电基板一、平行取向层、正性聚合物稳定胆甾相液晶层、正性胆甾相液晶层和透光导电基板二。
聚合物稳定胆甾相液晶(PolymerStabilized CholestericTexture,PSCT)中聚合物在液晶中以聚合物网络结构的形式存在,能够大大降低聚合物和液晶之间的相互作用,其中液晶分为正性液晶和负性液晶两大类,本发明中使用正性液晶的聚合物稳定胆甾相液晶命名为正性聚合物稳定胆甾相液晶。
本发明中正性胆甾相液晶指的是由正性液晶形成的胆甾相液晶。
优选地,所述正性胆甾相液晶层使用的正性液晶与正性聚合物稳定胆甾相液晶层使用的正性液晶相同。使用相同的正性液晶能够避免两层结构中的物质由于相互混合而对智能窗的性能造成影响。
优选地,所述正性胆甾相液晶层使用的手性掺杂剂与正性聚合物稳定胆甾相液晶层使用的手性掺杂剂手性相同。使用手性相同的掺杂剂能够避免两层结构中的物质由于相互混合产生手性相消而对智能窗的性能造成影响。
优选地,所述正性聚合物稳定胆甾相液晶层由包括2%~10%的聚合单体、0.1%~2%的光引发剂、8%~20%的手性掺杂剂、68%~89.9%的正性液晶的原料经光固化制得。
优选地,所述正性胆甾相液晶层包括8%~20%的手性掺杂剂和80%~92%的正性液晶。
其中,聚合单体可以是HCM008、HCM009等;光引发剂可以是Irgacure-651、Irgacure-819等;手性掺杂剂可以是S1011、R811等;正性液晶可以是HTW138200-100、E7等。
优选地,所述正性聚合物稳定胆甾相液晶层的厚度为5~50μm。
优选地,所述正性胆甾相液晶层的厚度为5~50μm。
优选地,还包括电源组件,所述透光导电基板一和所述透光导电基板二分别与所述电源组件的两极电性连接。
本发明还提供一种上述的多稳态电响应智能窗的制备方法,包括以下步骤:
取或制备透光导电基板一,在所述透光导电基板一的表面制备正性聚合物稳定胆甾相液晶层;
将透光基板一制备有正性聚合物稳定胆甾相液晶层的一侧与透光导电基板二相对设置,制备成液晶盒;
在所述液晶盒中填充正性胆甾相液晶,以形成正性胆甾相液晶层。
本发明的有益效果是:
本发明提供一种多稳态电响应智能窗,在未接入电压时,正性聚合物稳定胆甾相液晶层和正性胆甾相液晶层的液晶分子呈平行于透光导电基板的胆甾相排列,此时智能窗为有色透明状态;当接入电压时,正性胆甾相液晶层的液晶分子会重新排列为焦锥态,而正性聚合物稳定胆甾相液晶层中的液晶分子由于受到聚合物网络的限制仍然保持原取向排列,此时智能窗为有色模糊状态;当进一步增大接入电压时,正性聚合物稳定胆甾相液晶层和正性胆甾相液晶层的液晶分子均呈现焦锥态排列,此时智能窗为无色模糊状态;当接入的电压足够大时,正性聚合物稳定胆甾相液晶层和正性胆甾相液晶层的液晶分子均垂直于透光导电基板排列,此时智能窗为无色透明状态。相较于单独使用胆甾相液晶层和单独使用聚合物稳定胆甾相液晶层的技术方案,本发明的技术方案能够在不使用双频液晶的情况下获得不加电时稳定的散射状态并且可以回复到初始状态,其次本发明的多稳态电响应智能窗具有多样化的透光状态,能够满足人们工作生活中的各种需求,制作简单,模式丰富,节能环保的特点,在车窗玻璃,家居玻璃窗,玻璃幕墙等领域有着较好的应用前景。

参见图2,在接入电压U=0V时,正性聚合物稳定胆甾相液晶层3和正性胆甾相液晶层4的液晶分子呈平行于透光导电基板的胆甾相排列,此时智能窗只能反射一部分可见光,对其他波段的光无影响,呈有色透明状态。
参见图2,在接入电压U=22v时,正性胆甾相液晶层4的液晶分子由原来平行于透光导电基板的取向转变为焦锥态取向,而正性聚合物稳定胆甾相液晶层3中的液晶分子由于聚合物网络6的存在仍然维持平行于透光导电基板的胆甾相排列,此时智能窗呈有色模糊状态,并且关闭外接电压后,该智能窗能够保持在有色模糊状态。
参见图3,在接入电压U=30V时,随着接入电压的增大,正性聚合物稳定胆甾相液晶层3中的液晶分子转变成焦锥相排列,此时智能窗呈无色模糊状态。
参见图4,当进一步加大加入电压,接入电压=130V时,正性聚合物稳定胆甾相液晶层3和正性胆甾相液晶层4的液晶分子均垂直于透光导电基板排列,此时智能窗能够透过可见光,呈现无色透明状态,并且关闭外接电压后,智能窗能够回复至有色透明状态。
