Description
Technical Field
The invention relates to a method for controlling the movement of liquid metal in ionic liquid by using laser.
Background
Liquid metal refers to an amorphous metal that can be viewed as a mixture of a positively ionic fluid and a free electron gas. Liquid metal is also an amorphous, flowable liquid metal.
Liquid metals have unique physical and chemical properties that are clearly distinct from traditional molecular solvents and ionic liquids. In recent years, gallium-based liquid metals represented by gallium-indium alloys and gallium-indium-tin alloys have shown great potential in research and application in many fields such as the electronic industry, microfluidic, low-dimensional material manufacturing, biomedicine, flexible robots and the like because of their non-toxic, suitable liquid temperature ranges and characteristic bonding structures. The self-driven and deformable gallium-based liquid metal prepared by the subject group of the national Liu Jing professor draws wide attention internationally and shows important value, the power of the self-driven liquid metal is derived from hydrogen discharged by the participation of swallowed materials such as aluminum and the like in chemical reaction, and the liquid metal can do uncontrollable autonomous movement under the pushing of gas in a one-dimensional preset track[1]. Uncontrolled autonomous three-dimensional movement of metal-containing particles in aqueous solutions has been reported[2]。
Controlled movement of metal particles has also been reported. Oxygen generated by decomposing hydrogen peroxide on the surface of the liquid metal under photocatalysis can also push the liquid metal to move along a one-dimensional preset orbit in the hydrogen peroxide solution. The energy of light can be adjusted and controlled in the process,Controlling the moving speed of the liquid metal under the series of conditions such as hydrogen peroxide concentration[3]. Besides the chemical fuel driving mechanism of the generated gas, the electric field and the magnetic field preset in the two-dimensional plane can also control the liquid metal to move controllably. The controlled two-dimensional planar motion of solid particles in aqueous solutions under the control of illumination has been reported[4]。
The ionic liquid is a novel green solvent consisting of anions and cations, and is widely applied to the fields of materials, energy sources, chemical engineering, medicines and the like due to unique physical and chemical properties. At present, the metal-ion-containing liquid is regarded as a novel soft substance functional material because the metal-ion-containing liquid has excellent physicochemical properties of the ionic liquid and unique optical, electric and magnetic properties of metal. However, the movement of the current liquid metal in solution has the following disadvantages:
1. the three-dimensional motion of the liquid metal is uncontrollable;
2. the controllable motion of the liquid metal is limited to a two-dimensional plane;
3. the controlled movement of liquid metals in solution is limited to aqueous solutions.

and (4): the large bubbles carry the liquid metal to rise, and the movement direction of the liquid metal and the bubble combination body is controlled by regulating and controlling the laser irradiation part.
Further, the ionic liquid in the step (1) is formed by cation Am+And an anion Bn-The composition is as follows:
Am+is a 1-ethyl-3-methylimidazolium cation;

Further, the laser in step (2) has a wavelength of 200nm, which is generated by a laser having a power of 0.05W.
Further, the large bubble radius was 0.1 mm.
During control, the liquid metal is attached to the large bubbles to move upwards and then fall after being separated from the large bubbles; the phenomenon that metal droplets are adsorbed on large bubbles and rise with the large bubbles is difficult to observe when a surfactant is not added into an aqueous solution, because the surface of liquid metal in the aqueous solution is hydrophilic and cannot be adsorbed on the large bubbles. In the selected ionic liquid, the liquid metal is lyophobic and can be adsorbed on the large bubbles. As shown in fig. 1: the liquid metal temperature increases with longer laser irradiation time and increased laser power. As shown in fig. 2: the large bubbles can carry liquid metal to suspend in the solution or carry the liquid metal to move along the Z-axis direction; the liquid metal can be pushed to move along the laser irradiation direction by the small bubbles which are reversely sprayed at the liquid metal part irradiated by the laser.
