Abstract

The invention discloses an infrared laser driven graphene-based hydrogel motor and a preparation method thereof. The preparation method comprises the following steps: completing the packaging of oxidized graphene by using in situ polymerization and a gelation process of hydrogel; storing a liquid fuel with a low boiling point in a gel substrate of the motor by using an oil-in-water emulsion template method; then forming in a mold by adopting a casting process. The graphene-based hydrogel motor disclosed by the invention is a fuel self-contained type infrared laser driven hydrogel motor, and has good regulation performance, so that the control for motor motion speed is realized by changing infrared light intensity; the control for motor motion direction is realized by changing the irradiation position of infrared laser. Moreover, the graphene-based hydrogel motor disclosed by the invention is the fuel slef-contained type motor, and an additional fuel in the environment does not need to be consumed in the driving process, so that the application range of the micro motor is greatly expanded.

Description

technical field [0001] The invention relates to the field of intelligent polymer materials, in particular to an infrared laser-driven hydrogel motor based on the infrared absorption effect of graphene oxide and an emulsion template method and a preparation method thereof. Background technique [0002] Self-propelled miniaturized motors have attracted widespread interest due to their diverse propulsion systems, low-energy manufacturing methods, and broad practical application prospects. At present, there are many works exploring the application of micro-motors, such as: using micro-nano motors for drug or protein transport, applying micro-motors to the field of environmental restoration, and using micro-motors for biological detoxification, etc. Chemical propulsion micro motors rely on chemical reactions to generate air bubbles to achieve self-propulsion. They are driven in fuel pools, have strong driving capabilities, and can perform a variety of complex tasks. This kind of ...
