Description

A kind of preparation method of light-colored conductive nano-powder material technical field The invention belongs to the technical field of chemical industry, and in particular relates to a preparation method of a light-colored conductive nano-powder material. Background technique Zinc oxide is a semiconductor optoelectronic material with a wide range of applications. Its band gap at room temperature is 3.37eV, and its exciton binding energy is as high as 60meV. Aluminum-doped zinc oxide (ZincAluminiumOxide, referred to as ZAO) is a replacement solid solution formed by zinc oxide and aluminum oxide. It not only has good ultraviolet absorption performance and high chemical stability, but also has light color, high visible light transmittance, and good electrical conductivity. It can be widely used in antistatic coatings, rubber and plastics, etc., and has a tendency to replace ITO (In2O3:Sn) materials with good conductivity but expensive. At present, the research on nan...
