Abstract

The invention proposes a water-soluble fluorescent liquid metal material, which uses liquid metal as a base material, covers fluorescent dyes, and modifies the surface of a polymer material to increase the hydrophilicity of the material. The mass fraction of liquid metal in the material is 0.1-5 %; the solubility of the water-soluble fluorescent liquid metal material in water is greater than or equal to 10g / L. The invention also proposes a preparation method of the water-soluble fluorescent liquid metal material. The water-soluble liquid metal material proposed by the present invention has further expanded functions and properties compared with the previous macro-scale non-water-soluble liquid metal material, which greatly reduces the biocompatibility of the liquid metal material and the compatibility with different substrate materials, especially paper. The wettability of the material also maintains the original properties of the liquid metal material.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a water-soluble liquid metal and its preparation. Background technique [0002] In recent years, liquid metals have entered people's field of vision as an emerging material. Liquid metals usually refer to metals that are liquid at room temperature, which not only has good fluidity, but also has excellent electrical and thermal conductivity of metals. However, there are not many metals that can maintain a liquid state at or near room temperature, mainly mercury, gallium and its alloys, alkali metal alloys, rubidium, cesium, francium, etc. Among these metals, rubidium, cesium, and francium are radioactive The chemical properties of metals and alkali metal alloys are very active, and the environmental requirements are extremely strict when they are stored and used, so they are difficult to be used by people in daily life. Mercury is the most common liquid metal. It is wi...
