▎ 摘　　要

NOVELTY - Light-responsive liquid-gas phase change composite material comprises dispersion medium and dispersed phase. The dispersed phase is uniformly dispersed in a dispersion medium. The dispersion medium includes silicone rubber. The dispersed phase includes low-boiling point liquid and multifunctional filler, and the low-boiling point liquid is uniformly dispersed in the dispersion medium in the form of droplets. The mass ratio of the dispersed phase and the dispersion medium is 1-40:100, preferably 6-33:100, the particle size of the droplets is 50-200 microm. The silicone rubber includes Ecoflex 00-50 (Aliphatic-aromatic copolyester), Ecoflex 00-30 (Aliphatic-aromatic copolyester), Dragon skin 30 (Silicones with high performance addition cure liquid silicone compound), Beshow Skin 30, and T10. USE - The light-responsive liquid-gas-phase change composite material is useful for preparing light-responsive device (claimed). ADVANTAGE - The method is simple and easy to operate, and the multifunctional filler used has good photothermal conversion effect. The light-responsive liquid-phase change composite material can be remotely deformed by near-infrared light, and the obtained light-responsive device has light response, large deformation, high thermal conductivity and is economical. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for preparing light-responsive liquid-gas phase change composite material, comprising reacting mixed reaction system comprising silicone rubber prepolymer, silicone rubber prepolymer curing agent, low-boiling point liquid and multifunctional filler; and (2) method preparing a light-responsive device, comprising preparing mixed reaction system formed by mixing the first mixture and the first mixture, using three-dimensional (3D) printing technology, injecting mixed reaction system into a feeding device for 3D printing to prepare a light-responsive device.
