摘要：

本发明属于纳米复合材料技术领域,具体为一种红外光致形变液晶高分子纳米复合材料及其制备方法。该复合材料由含有偶氮苯及其衍生物的液晶高分子和稀土发光纳米粒子组成,所用的液晶高分子由聚合物单体和交联剂,在光引发剂或者热引发剂存在的条件下,通过光聚合反应或者热聚合反应而获得。该复合材料可在红外光的照射实现光致形变,停止光照可恢复形变。该液晶高分子纳米复合材料可用于微执行器件、人工肌肉、生物芯片等领域。

Abstract：

The invention belongs to the technical field of nano composite materials, and particularly relates to an infrared photodeformable liquid crystal high-polymer nano composite material and a preparation method thereof. The composite material comprises liquid crystal high polymers containing azobenzene and derivatives thereof, and rare-earth light-emitting nano particles, wherein the liquid crystal high polymers are prepared from polymer monomers and a cross-linking agent through photopolymerization or thermal polymerization in the presence of a photoinitiator or a thermal initiator. The composite material can realize photoinduced deformation under the irradiation of infrared light, and can restore after stopping irradiation. The liquid crystal high-polymer nano composite material can be used in the fields of micro actuators, artificial muscles, biochips and the like.
