Problems solved by technology

However, these tiny motors still have some unavoidable disadvantages when making them actually used in real environments
First of all, most of the existing micro motors are manufactured by electrochemical deposition method and particle beam spraying method. These manufacturing methods are relatively complicated and require high equipment. limits
Second, due to the small size of the existing micromotors, it is more difficult to further modify and improve them, thus restricting their functionalization and functional integration.
Third, due to the limitation of its size, it is difficult for nanomotors to overcome the influence of Brownian turbulence and perform Newtonian motion during motion.
Fourth, most of the existing micro-motors are obtained by modifying and modifying some inorganic particles. They belong to rigid motors. Rigid motors will not yield under the action of external force, which is not enough to cope with changes in the external environment and maintain a state of motion.

Abstract

The invention discloses a soft gel self-driving micro motor and a preparation method thereof. The preparation method mainly comprises the following steps: dispersing monomers, a cross-linking agent, an initiator and a catalyst which form a soft gel material in an aqueous solution by utilizing an in-situ polymerization method; forming the aqueous solution which is mixed uniformly into a shape required by a motor in a mould; loading catalyst solution on the gel by adopting a simple injecting method after high vacuum silicone grease protection treatment is performed; adsorbing the catalyst solution by utilizing the hydrophilic property of the gel to complete the manufacturing process of the soft gel-based micro self-driving motor. The self-driving process of the micro motor is realized in hydrogen peroxide solution. The method disclosed by the invention is easy to operate, low in equipment requirement, and suitable for scale production. The obtained soft gel-based micro self-driving motor can be used in the field of environment, such as water treatment, and meanwhile, provides a feasible driving ideal for the development of an intelligent soft robot.

Description

technical field [0001] The invention relates to the field of intelligent polymer materials, in particular to a soft gel self-driven micro motor and a preparation method thereof. Background technique [0002] Developing new self-propelled micromotors and exploring their multiple applications in actual production is a current research hotspot. Most of the micromotors generate oxygen by catalyzing hydrogen peroxide, and use the oxygen bubbles to propel themselves forward, so as to obtain a micro-device that can swim in a solution containing hydrogen peroxide. Micromotors with different propulsion mechanisms have been explored for many applications in drug and protein transport, oil removal, biological detoxification, and water treatment. However, these tiny motors still have some unavoidable disadvantages when making them actually applied in the real environment. First of all, most of the existing micro motors are manufactured by electrochemical deposition method and particle...
