Abstract
The present invention provides a fluorine-containing liquid crystal polymer of Formula (1). The present invention also discloses a fluorine-containing liquid crystal elastomer, which comprises a copolymer of a fluorine-containing liquid crystal polymer of Formula (1) with a near-infrared dye of Formula (2). The fluorine-containing liquid crystal elastomer of the present invention shrinks due to the photothermal conversion effect of the material under the irradiation of near-infrared light, and thus is widely applicable to the field of actuators. The fluorine-containing liquid crystal polymer of the present invention introduces fluorine-containing segments into the cross-linked network of the liquid crystal polymer, to improve the mechanical performance of the material, and greatly extend the service time of light-controlled actuators.
