Description

technical field [0001] The invention relates to a preparation method in the technical field of nanocomposite materials, in particular to a preparation method of copper sulfide nanomaterials. Background technique [0002] Sulfide semiconductor nanomaterials have attracted people's attention because of their novel photoelectric physical properties, partial electronic conductivity and partial ion conductivity, and can be used as superionic conductors. [0003] Copper sulfide is an important transition metal sulfide, based on the complex structure and chemical valence of copper sulfide, so they are widely used in thermocouples, optical recording, optical filters, solar cells, dry powder coatings and fluorescent materials, etc. In addition, the fast ionic conductivity of copper sulfide at high temperature has also become a research hotspot. If the copper sulfide material is nanosized and has a relatively regular spherical crystal appearance, it can be used in mechanical lubricat...
