Description

technical field [0001] The invention belongs to the field of nanotechnology, and in particular relates to a method for preparing network-structured nanometer zinc oxide. Background technique [0002] Nano-zinc oxide is a multi-functional new inorganic material, and its particle size is about 1-100 nanometers. Due to the miniaturization of crystal grains, the surface electronic structure and crystal structure change, resulting in surface effects, volume effects, quantum size effects and macroscopic tunnel effects that macroscopic objects do not have, as well as high transparency and high dispersion. In recent years, it has been found that it exhibits many special functions in catalysis, optics, magnetism, mechanics, etc., making it have important application value in many fields such as ceramics, chemical industry, electronics, optics, biology, medicine, etc. Specificity and use of comparisons. Nano-zinc oxide can be used in the fields of textiles and coatings for ultraviol...
