NOVELTY - Preparing double layer composite material bionic motor behavior driver comprises e.g. (i) adding polyethylene glycol, caprolactone and stannous octoate into a three-necked flask, mixing, introducing nitrogen gas for 30 minutes, stirring the mixture, cooling, then mixing with methacrylic anhydride, pouring into a single-necked flask, introducing nitrogen gas, placing the product in a vacuum oven and drying to obtain acrylate-modified polyethylene glycol-polycaprolactone block, (ii) adding acrylate-modified polyethylene glycol-polycaprolactone block, photothermal conversion monomer, thermal initiator and N,N-dimethylformamide into the flask, ultrasonicating, placing the mixture in an oven, and soaking in deionized water, and (iii) mixing isopropylacrylamide, deionized water, and photoinitiator into a glass bottle, stirring to dissolve, and freezing to obtain final product. USE - The composite material is useful in the fields of tissue engineering, wound directional therapy and electronic skin sensing; in constructing software robot and device. ADVANTAGE - The composite material: has fast response, reusability and excellent bionic movement ability; imitates the palm holding objects and finger gesture display; simulates the blooming of flowers; and method: solves the problem of unidirectional drive of ordinary drives. DETAILED DESCRIPTION - Preparing double layer composite material bionic motor behavior driver comprises (i) adding polyethylene glycol, caprolactone and stannous octoate into a three-necked flask, mixing, introducing nitrogen gas for 30 minutes, then stirring the mixture at 140 ℃ for 24 hours under nitrogen atmosphere, cooling, then mixing with methacrylic anhydride, pouring into a single-necked flask, introducing nitrogen gas for 30 minutes, then stirring the mixture at 130 ℃ for 7 hours, placing the product in a vacuum oven and drying to obtain acrylate-modified polyethylene glycol-polycaprolactone block, (ii) adding acrylate-modified polyethylene glycol-polycaprolactone block, photothermal conversion monomer, thermal initiator and N,N-dimethylformamide into the flask, ultrasonicating for 15 minutes, placing the mixture in an oven at 65 ℃ for 1.5 hours, cooling, and soaking in deionized water for 4 hours until the N,N-dimethylformamide in the product is replaced by water to obtain product, and (iii) mixing isopropylacrylamide, deionized water, and photoinitiator into a glass bottle, stirring to dissolve at 25 ℃, then pouring the mixture onto the surface of the optical drive layer, freezing in a -20 ℃ environment until it crystallizes completely, covering the surface of all crystallized samples with transparent glass, and performing photoinitiator reaction under wavelength of ultraviolet light obtaining temperature-sensitive driving layer, to obtain bilayer composite material bionic motor behavior driver.
