Embodiment 1

[0039] Fabrication of photothermal actuated robots by photoreduction.

[0040] The composite nanomaterial of graphene oxide and gold nanorods is used as the basic material for the preparation of photothermal-driven robots, and the pattern design of the robot can be realized through light carving reduction; Graphene oxide in the actuator region, resulting in several photoactuator components with photothermal response.

Embodiment 2

[0051] The response wavelength of the photothermally driven robot is regulated by adjusting the diameter-to-length ratio of gold nanorods.

[0052] The photothermal driven robot of the present invention has wavelength response characteristics, that is, it only responds to the laser-driven light source of a specific wavelength. This response wavelength is determined by the diameter-to-length ratio of the gold nanorods in the composite film. Therefore, by regulating the synthesis of AgNO 3 By changing the diameter-to-length ratio of the gold nanorods by changing the amount of the solution, the response wavelength of the photothermally driven robot to the driving light source (that is, the resonance wavelength of the plasmons excited on the gold nanorods) can be adjusted.

Abstract

The invention discloses an optothermal responsive material, a method used for preparing photo-thermal driven robot from the optothermal responsive material, and applications thereof, belongs to the technical field of light drivers, and more specifically discloses a composite film obtained through introduction of a graphene oxide and gold nanometer rods into polymethyl methacrylate film. The obtained double-layer film is taken as a raw material film used for preparing a robot; a commercial light disk lightscribe CD-ROM drive is adopted for laser scanning modification of the upper layer composite film of the raw material film so as to obtain a patterned robot structure; in scanning, laser is adopted for photoreduction of CD-ROM drive regions in the structure of the robot, so that the composite film at the CD-ROM drive regions is provided with high light absorbance and high thermal conductivity, and a high efficiency CD-ROM drive assembly is formed by the composite film and lower layer PMMA film. In driving of the robot under illuminating using a light source, the thermal expansion coefficient of the composite film at the CD-ROM drive regions after reduction is much lower than that ofthe PMMA film, so that the high efficiency CD-ROM drive assembly bend toward the side of the composite film, and robot deformation of moving is driven.

Description

technical field [0001] The invention belongs to the technical field of optical drives, and specifically relates to a photothermal response material and a photothermal drive robot obtained by processing a composite film of graphene oxide and gold nanorods reduced by the photoresponsive material by using the photo-thermal effect. The robot drives. [0002] technical background [0003] Light actuators are the core components of light-driven robots. The multilayer structure optical drive is one of the typical representatives. Its basic driving principle is to use the photothermal effect to cause the expansion or contraction of materials; that is, materials with different thermal expansion coefficients are prepared into a multilayer structure. The side of the material with a smaller coefficient is bent, and then the stress generated by the material deformation is used to drive the robot to achieve driving effects such as folding, grasping, and movement. Accordingly, this type o...
