Description

technical field [0001] The invention belongs to the field of materials, and relates to a preparation method of a micronano silver-based material and the micronano silver-based material. Background technique [0002] Among all kinds of metal particles, silver particles with micron and nanometer sizes have attracted people's attention since their appearance, not only because of their unique electronic, optical, and catalytic properties, but also because of their good antibacterial properties and biocompatibility. And the surface is easy to modify and many other advantages. Micro-nano silver particles have been widely used in photolithography, biomedical materials, chemical catalysts, ceramic materials, conductive pastes, sewage treatment, construction materials, lubricants, light-absorbing materials, coatings, sensors, and high-performance electrode materials. [0003] In order to meet different needs, people have been exploring new methods of preparing micro-nano silver part...
