1. A method for preparing a fluorine-containing liquid crystal elastomer, comprising steps of:
(1) under a protective atmosphere, reacting a fluorine-containing liquid crystal polymer of Formula (1) and a near-infrared dye of Formula (2) in the presence of Grubbs catalyst in an organic solvent at 58-65° C. for 1.5-2.5 h to obtain a preliminarily cross-linked polymer; and
(2) applying an external force to the preliminarily cross-linked polymer, and allowing the preliminarily cross-linked polymer to react at 110-130° C. under the action of the external force, to obtain the fluorine-containing liquid crystal elastomer after the reaction is completed, wherein the compounds of Formulas (1)-(2) are shown below:
where X=5-12.
