Liquid crystal gels, exhibiting promising applications in novel light scattering displays, face the problem of the inherent contradiction between the applied voltage and the contrast, which are the two most basic and crucial parameters for displays. Regretfully, improvement of the applied voltage always means the sacrifice of contrast and vice versa, related to the morphology of the gel fibers. Alternatively, we propose an approach to easily regulate the electro-optical properties to meet the needs of different applications, towards either lower applied voltage or higher contrast, based on kinetics-controlled hierarchy self-assembly. Thin rod-like and thick helical gel fibers are formed when cooling the liquid crystal gel in water and air respectively, leading to significantly different electro-optical properties. This method not only facilitates the large-scale manufacture and application of light scattering displays, but also provides a practical application using the newly developed theory of kinetics-controlled self-assembly. © 2021 Society of Chemical Industry

通过动力学控制的层次自组装轻松调节液晶凝胶的电光特性

液晶凝胶在新型光散射显示器中展现出广阔的应用前景，但它面临着施加电压和对比度之间固有矛盾的问题，这是显示器的两个最基本和最关键的参数。遗憾的是，施加电压的提高总是意味着对比度的牺牲，反之亦然，这与凝胶纤维的形态有关。或者，我们提出了一种基于动力学控制的层次自组装来轻松调节电光特性以满足不同应用需求的方法，即降低施加电压或提高对比度。液晶凝胶分别在水和空气中冷却形成细棒状和粗螺旋状凝胶纤维，导致电光性能明显不同。该方法不仅有利于光散射显示器的大规模制造和应用，而且为利用新发展的动力学控制自组装理论提供了实际应用。© 2021 化学工业学会
