Abstract:
A novel kind of super strong liquid crystalline physical gel with high Tsg( gelsol transition temperature) and tensile strength is reported in this paper, which is obtained from adding a new kind of POSScore dendrimers into host liquid crystals with photoresponsive agents containing azochromophores. The azophotoresponsive agents provide the liquid crystalline physical gel photoresponse properties and the host liquid crystals provide the liquid crystalline physical gel thermoresponse 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.
