Embodiment 1

[0033] This embodiment provides a method for preparing a liquid metal-micro-nano particle mixture, which includes the following steps:

[0034] S1, 1g of copper nanoparticles with a particle size of 50nm and 19g of gallium-indium alloy (Ga 75.5 In 24.5 ) are respectively added into an aqueous hydrochloric acid solution having the same volume as the gallium-indium alloy and having a pH value of 1;

[0035] S2. Stir the aqueous hydrochloric acid solution added with gallium-indium alloy and copper nanoparticles with a magnetic stirrer for 5 minutes, and let it stand to make it divided into two layers, namely the liquid metal-micro-nanoparticle mixture located in the lower part and the aqueous hydrochloric acid solution located in the upper part;

[0036] S3, removing the aqueous hydrochloric acid solution in the upper part, and then vacuum-drying the liquid metal-micronano particle mixture in the lower part at room temperature for 1 hour to obtain the final product.

[0037] It...

Embodiment 2

[0039] This embodiment is basically the same as Embodiment 1, the only difference is that the pH value is 3.

Embodiment 3

[0041] This example is basically the same as Example 1, the only difference being that the hydrochloric acid aqueous solution in Example 1 is replaced by sulfuric acid aqueous solution.

Abstract

The invention belongs to the field of liquid metallic materials, and particularly relates to a method for doping micro nanoparticles into liquid metal and application of a liquid metal-micro nanoparticle mixture. The method comprises the steps that the micro nanoparticles and the liquid metal with the mass ratio of the micro nanoparticles to the liquid metal being 1:(9-19) are added into an acidic, alkaline or conductive solution, and stirring is conducted, so that the micro nanoparticles are doped into the liquid metal, then the acidic, alkaline or conductive solution is removed. The invention further provides the liquid metal-micro nanoparticle mixture prepared through the method and application of the liquid metal-micro nanoparticle mixture in the aspect of preparing a high-thermal-conductivity liquid metal-micro nanoparticle mixing fluid or paste mixture, or in the aspect of preparing a magnetic-liquid liquid metal-micro nanoparticle mixing fluid or paste mixture. According to themethod for doping the micro nanoparticles into the liquid metal, the process is simple, properties of the liquid metal and the micro nanoparticles can be organically combined, original properties of the liquid metal can also be maintained, the functions of liquid metal materials are enriched, and the application field of the liquid metal is expanded.

Description

technical field [0001] The invention belongs to the field of liquid metal materials, and in particular relates to a method for doping liquid metal with micro-nano particles and an application thereof. Background technique [0002] Liquid metal is a kind of low melting point metal single substance and binary or multiple alloys, such as gallium with a melting point near room temperature and an alloy of gallium with one or more of indium, tin, and zinc. As a metal system with highly disordered internal microstructure arrangement, liquid metal is obviously different from conventional fluid and solid metal in essence. In terms of macroscopic properties, liquid metal not only has the characteristics of easy deformation and flow of fluid, but also has the excellent thermal and electrical conductivity of metal materials. In recent years, with the deepening and comprehensive development of liquid metal research, these advantages of liquid metal have attracted more and more attention...
