可拉伸显示器在智能通讯、可穿戴及可植入显示设备等领域有广泛的应用前景。液晶因其“流动而有序”的本质特性在显示领域普遍使用,但此本质特性导致液晶材料无固定形状、排列方式易受外力场影响而改变、显示器件结构复杂，仍未应用于可拉伸显示领域。本项目利用POSS核的六面体八臂新型凝胶因子的多级自组装特性制备超分子液晶凝胶，极低的凝胶因子添加量（≤0.5wt%）即可赋予液晶材料超强的机械强度，获得可拉伸液晶显示器（拉伸形变≥145%），从本质解决了液晶显示材料“形变—响应”的固有矛盾。通过对静态、循环加载以及电场驱动条件下液晶化合物的相行为、凝胶因子的多级自组装行为、凝胶网络在液晶客体分子中的形态变化规律、超分子液晶凝胶的响应等特性的一系列演变规律的研究，阐明宏观外力场对微观弱相互作用下的自组装及有序性、响应性的影响规律，获得电控可拉伸液晶显示器件，使传统液晶显示材料在可拉伸显示领域焕发新的生命活力。

Stretchable displays have broad application prospects in the new generation of intelligent communication equipments, wearable electronic instruments and implantable displays. Liquid crystals have wide applications in display field because of its essential property of being oriented while still can flow. However, this essential property results in liquid crystal materials having no fixed geometry, arrangement of which being influenced easily by external force field, and its display devices having complicated structures, and until now no applications in stretchable displays are reported. This project uses the hierarchical self-assembly properties of novel eight arm hexahedral POSS core gelators to prepare supramolecular liquid crystal gels, and the extreme low addition of gelators (≤0.5 wt%) provides liquid crystal high mechanical strength, that can be used to prepare stretchable displays (tensile deformation≥145%), which essentially settles the inherent contradiction of “deformation-response” in liquid crystal materials. This project aims to research the phase behaviors of liquid crystals, the hierarchical self-assembly behaviors of gelators, the morphology change of gel networks in liquid crystals and the response properties of supramolecular liquid crystal gels under static state, cyclic loading and electric driven conditions, to clarify the influence rule of macroscopic external force on the self-assemble, arrangement order and response properties based on the microcosmic weak interaction, in order to obtain electric control stretchable liquid crystal displays, which could provide traditional liquid crystal display materials fresh life and energy in the field of stretchable displays.
