摘要:
将一种具有自组装特性的新型POSS核凝胶因子添加到含有偶氮苯光响应剂的液晶基体中,获得具有高Tsg(凝胶-溶胶转变温度)和抗张强度的超强液晶物理凝胶。偶氮苯光响应剂赋予该液晶物理凝胶波长响应特性,液晶基体赋予其温度响应特性,所获液晶物理凝胶不同的响应状态之间具有显著的对比度差异,使其无需使用传统液晶显示器中必不可少的偏振片也能显示出清晰的图像信息。偏振片的省去极大地简化了显示器件的结构,使得该液晶物理凝胶超强的力学性能得以充分利用,用以制备一种新型的可拉伸液晶显示器件,该显示器件在拉伸到原始长度的145%时仍能清晰地显示原有的图像信息。由于该器件的制备过程简单,可以通过包括滴涂、旋涂以及高温喷涂等在内的传统加工工艺制备获得,相信全拉伸型液晶显示器件在将来可以获得广泛的应用。
Abstract:
 A novel kind of super strong liquid crystalline physical gel with high Tsg( gelsol transition temperature) and tensile strength is reported in this paper, which is obtained from adding a new kind of POSScore dendrimers into host liquid crystals with photoresponsive agents containing azochromophores. The azophotoresponsive agents provide the liquid crystalline physical gel photoresponse properties and the host liquid crystals provide the liquid crystalline physical gel thermoresponse properties. So that the result liquid crystalline physical gels show clear contrast differences at different phases, so that polarizers in the devices could be abandoned to greatly simplify the device structures. Combing with the strong mechanical properties of the supramolecular liquid crystalline gels, a novel kind of stretchable liquid crystalline light scattering display is prepared in this paper, which can clearly show the original image information even be stretched to 145% times of the original length. Considering the preparation process of such device is quite simple, and traditional processing methods including dispensing coating, spin coating and high temperature spray coating are all suitable to be used, we believe such kind of stretchable liquid crystalline displays will get extensive application in the future.
