Embodiment Construction

[0033] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0034] A multifunctional liquid metal, including liquid metal, the liquid metal is magnetic, and there is no film on the surface of the liquid metal.

[0035] Such as figure 1 Shown, a kind of preparation method of multifunctional liquid metal is characterized in that, comprises the following steps:

[0036] (1) Provide a base, place alloy powder on the base, roll the liquid metal on the alloy powder, so that the liquid metal is evenly wrapped around the alloy powder, and obtain a magnetic liquid metal; the liquid metal is preferably gallium-indium alloy, but not limited to Gallium indium alloy can also be one of gallium indium tin alloy and...

Abstract

The invention relates to a multifunctional liquid metal, which takes the liquid metal as the core, the liquid metal has magnetism, and there is no thin film on the surface of the liquid metal. The present invention also relates to a method for preparing a multifunctional liquid metal, comprising the following steps: (1) providing a base, placing alloy powder on the base, rolling the liquid metal on the alloy powder, so that the liquid metal is evenly wrapped around the alloy powder, Obtaining magnetic liquid metal; (2) adding hydrochloric acid to the magnetic liquid metal for treatment, and a thin film is formed on the surface of the magnetic liquid metal; (3) providing a channel in which an electrolyte solution is placed; (4) treating the magnetic liquid metal in step (2) The magnetic liquid metal is placed in the electrolyte solution, and DC power is applied; (5) The magnetic liquid metal breaks through the film and flows out, and drags the film to the cathode. When the magnetic liquid metal is separated from the film, the DC power is turned off. The invention increases the surface fluidity of the magnetic liquid metal.

Description

technical field [0001] The invention relates to a liquid metal, in particular to a multifunctional liquid metal and a preparation method thereof. Background technique [0002] Liquid metals generally refer to metals that can still maintain a liquid state at room temperature. Liquid metals can play an important role in soft robotics, pumps, micropipes, 3D printing, and more. The current pure gallium-based liquid metal at room temperature cannot be driven by a magnetic field because it is not magnetic. Later, liquid metal vesicles were prepared by wrapping a layer of nano-magnetic material particles on the outer surface of pure liquid metal, and then treated with concentrated hydrochloric acid, which can realize the magnetic drive of liquid metal at room temperature. However, such liquid metal vesicles are separated under the drive of an electric field and cannot move normally. In addition, a very important inherent property of liquid metal-surface fluidity is also destroyed...
