Recently, the Tsinghua University team in China first proposed the concept of "light liquid metal", and also invented a light-weight liquid metal material with strong plasticity, harmlessness (good biological safety), and a density lower than that of water. This material maximizes the characteristics of liquid metal. This material can maintain good material consistency and conductivity under temperature regulation, and can switch freely between a completely soft and hard state, which is the closest. " "Perfect" liquid metal.
Liquid metal, also known as "amorphous alloy" or "metallic glass", is a solid with an atomic structure similar to that in a liquid state. It has a special structure and properties and is a revolutionary new material. Compared with traditional crystalline materials, liquid metals have no defects such as vacancies, dislocations, and grain boundaries, and also have excellent properties such as high strength, high hardness, high finish, high elasticity, corrosion resistance, and wear resistance. At present, the liquid metal materials developed in the world have superior performance in many aspects to the "king of materials" graphene.
The light liquid metal exhibited in the study has many excellent functions, such as high electrical conductivity, magnetism, deformability, assembly stackability, high thermal conductivity, and flexible conversion characteristics between liquid and solid state. These are graphene's strengths. However, graphene is not easy to become liquid, which makes it less than liquid metal in many application scenarios.
In summary, the research results released this time have pushed the research of liquid metals forward a big step, which is expected to shake the dominance of graphene materials. Liquid metal is an upstart among metal materials, and it is an emerging sunrise industry. It is possible to gradually replace existing materials and produce breakthrough products. This will contain unlimited development potential and market space. Liquid metal will become the third generation of new materials after engineering plastics and light alloys. It can be widely used in consumer electronics, lithium batteries, 3D printing, flexible intelligent machines, vascular robots, etc. Promote trillion-scale market space.
