Description

一种液晶组合物及应用其的双稳态液晶调光器件
技术领域
本发明涉及液晶显示技术领域,尤其涉及一种液晶组合物及应用其的双稳态液晶调光器件。
背景技术
随着建筑理念的提高,传统玻璃功能相对单一,已无法满足现代建筑在资源利用、节能环保、智能控制、有益健康等方面提出来的前所未有的新要求。智能液晶调光玻璃,通过电场的作用,使玻璃光线的透过率及视物的清晰度发生改变,从而有效的控制紫外线、红外线的进入,清晰和雾态的切换,从而起到节能环保和保护隐私的作用,引起业内的广泛研究。
目前液晶调光玻璃的种类主要有PDLC智能调光玻璃、染料液晶调光玻璃和双稳态液晶调光玻璃。PDLC智能调光玻璃在不加电状态下呈现雾态,加电状态下呈现透明态,从而实现电控调光的作用。但是由于PDLC智能调光玻璃断电状态呈现雾态,因此更适合应用于隐私状态较多的场景,否则会相当耗电;另一方面PDLC智能调光玻璃的透明态依然雾度较大,存在视角问题。染料液晶调光玻璃可以实现光的明暗调节,但是应用于染料液晶调光玻璃的染料液晶成本很高且光稳定性较差;另一方面染料液晶是单稳态,维持另一态需要持续通电,电力成本较高。双稳态液晶调光玻璃包括两个零电场稳定的状态:使入射光基本上透射的透过态以及使入射光基本上散射的雾态,通过选取合适的驱动方式驱动双稳态液晶调光玻璃,可使其在透过态和雾态之间转换,从而实现调光的目的。既节能环保,也能减小触电等安全隐患,因此在幕墙、隔断、智能车窗等领域广泛应用。
但是双稳态液晶调光玻璃仍具有某些尚未克服的缺点,如工作温宽窄的问题等,因而使其应用场景受限,而影响双稳态液晶调光玻璃性能的因素主要有P态雾度、N-TB相的螺旋结构、N-TB相变温度、清亮点等,因此,我们需要选择合适的单体、双体和手性剂材料,充分考虑各组分之间的相容性,选择合适的比例,才能得到高性能宽温双稳态液晶组合物。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合本申请具体实施例对本申请技术方案进行清楚、完整地描述。显然,所描述的实施例仅是本申请一部分实施例,而不是全部的实施例,不用来限制本发明的范围。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
双介晶化合物(指分子中包含两个介晶基元的液晶化合物)作为双稳态液晶调光玻璃的重要组分,由于其具有的特殊结构,可以诱导第二向列相(扭曲-弯曲向列相,即N-TB相),加入手性向列相液晶后,可获得相对高的展曲弹性常数K11、相对低的弯曲弹性常数K33和相对低的挠曲弹性系数K22。当K33≈K22时,液晶分子可以直接从P态恢复到H态,达到完美的平面态,具有极小的雾度。因此P态的雾度与双介晶化合物的含量有直接关系,双体含量较低时P态通常具有高的雾度。另外,当K11/K22大于2时,N-TB相的螺旋结构相对稳定,因此通过调节K值可以实现透过态和雾态的双稳态。然而,当温度接近或低于N-TB相温度时,液晶会发生相变,液晶分子很难从H态恢复到P态,无法变透明。由专利CN109825309A和CN112130362A可知,向正介电常数向列相液晶中加入手性剂得到胆甾相液晶,再加入双介晶化合物,可实现P态雾度小于10%,雾态雾度大于85%。然而按照上述两个专利的组分及步骤进行操作测试时又发现清亮点均较低(<90℃),N-TB点高(>-15℃),此时当温度降低到-10℃时,H态很难恢复到P态,一直保持雾态状态,此外,清亮点较低时,也会导致高温工作中雾态雾度低且无法保持。
根据MichaelR. Tuchband和Min Shuai等人的文献(Double-helical Tiledchain structure the twist-bend liquid crystal phase in CB7CB)公开的研究结论发现随着双体的减少清亮点和N-TB点温度单调下降。因此虽然通过减少双体含量可以来降低N-TB相变温度,但是也会引起P态雾度升高以及清亮点下降,增加三环和四环液晶单体的含量来有效提高清亮点温度,但是在一定程度上也会提高N-TB点的温度、改变N-TB相的螺旋结构且对P态的雾度和FC态雾度稳定性也有一定影响。
由上述液晶组合物中各组分对双稳态液晶调光器件性能的影响,本申请为解决现有双稳态液晶调光器件工作温宽窄的问题,即:当工作温度低于-10℃时,双稳态液晶调光器件中的液晶分子在H态断电后很难回到P态,即断电后无法回到透明态;当工作温度较高且与清亮点相差小于20℃时,雾态雾度保持差,雾度低,继续升高温度雾态难以保持。本申请提供了一种液晶组合物,包括至少一种选自通式Ⅰ的化合物、至少一种选自通式Ⅱ的化合物、至少一种选自通式Ⅲ的化合物、至少一种选自通式Ⅳ的化合物以及至少一种手性化合物;
上述通式Ⅰ为R1-MG1-X-MG2-R2;其中:R1和R2各自独立地表示-H、-F、-Cl、-CN、-NCS或者任意一种C原子数为1-25的链烷基,作为优选的实施方案,所述C原子数为1-25的链烷基中的一个或多个H原子可以各自独立地被卤素或-CN取代,所述链烷基中的一个或多个不相邻的-CH2-可以各自独立地被-O-、-S-、-NH-、-N(CH3)-、-CO-、-COO-、-OCO-、-OCOO-、-SCO-、-COS-、-CH=CH-、-CH=CF-、-CF=CF-或-C≡C-替代,所述替代的方式不包含两个-O-彼此相邻;MG1和MG2各自独立地表示介晶基元;X为C原子数为1、3或5至40的直链或支链亚烷基基团,作为优选的实施方案,所述直链或支链亚烷基基团中的一个或多个不相邻的-CH2-可以各自独立地被-O-、-S-、-NH-、-N(CH3)-、-CO-、-COO-、-OCO-、-OCOO-、-SCO-、-COS-、-CH=CH-、-CH=CF-、-CF=CF-、-C≡C-或-CH(CN)-替代,所述替代的方式不包含两个-O-彼此相邻或两个选自由-OCO-、-SCO-、-OCOO-、-COS-、-COO-和-CH=CH-组成的基团彼此相邻。

将样品放置到MK2000控温台,常温快速升温到60℃后,稳定3min,改为5℃/min加热速率继续加热,当液晶完全清亮时记为清亮点;使温度快速下降到-30℃,稳定5min后,改为5℃/min加热速率加热升温,将发生相变(液晶颜色发生显著变化,从黑棕色变成棕黄色)的温度记为N-TB点,若降温到-30℃未有相变发生,说明N-TB点小于-30℃。
2)调光器件结构
所述双稳态液晶调光器件包括第一透明导电基板和第二透明导电基板,所述第一透明导电基板和所述第二透明导电基板彼此平行且相对设置以形成液晶盒;填充于所述第一透明导电基板和所述第二透明导电基板之间的所述液晶盒中的液晶层,所述液晶层包括上述所述的液晶组合物;所述双稳态调光器件的盒厚可根据雾度需求选择。其中,将液晶组合物灌注到所述液晶盒中后,应用365nm的UV低压汞灯在10mw/cm2的强度下照射调光器件60秒,使液晶组合物中的可聚合单体NOA65聚合。
3)雾度测试方法
将本申请中上述实施例中的液晶组合物分别真空灌注到20μmVA液晶盒中,完成封口后,准备测试。首先,打开WGT-S型雾度仪,光源稳定30min后开始测试。通过加一个合适的高电压,使液晶分子驱动到H态,断电50s后,点击测试按钮进行测试并读数记录透过态雾度;通过施加一个合适的低电压,使液晶分子从P态驱动到FC态,点击测试按钮进行测试并读数记录雾态的雾度。
