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.
