China invents a new type of high-conductivity nanopowder material

Chemical New Product Technology: The reporter learned from the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences that a green and environment-friendly high-conductivity nanopowder material has been successfully developed in this institute recently and has obtained the patent authorization from the State Intellectual Property Office. According to reports, this new type of material is called “high-conductivity aluminum-doped zinc oxide nanopowder” and has features such as high crystallinity, uniform doping, controllable morphology, and good dispersion and repeatability. The resistivity can be as low as 15Ω·cm. The material has broad application prospects in scientific research and industrial production, such as transparent conductive electrodes on electronic devices, conductive fillers in antistatic composite materials, and the like, which can be used for such nanopowder materials. One of the person in charge of this subject, Yang Xiaoniu, researcher of the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, stated that the preparation of this new type of nanopowder material is simple, easy, short cycle, low cost, no surfactant and template, but also Scale production. In addition, the invention also provides a new route for preparing monodisperse nanostructures for other transparent conductive oxides. It is understood that the demand for transparent conductive oxides has increased dramatically worldwide. Zinc oxide-based nanomaterials have become one of the most promising types of transparent conductive oxides due to their advantages of being non-toxic, low cost, and light color. Things. However, how to improve the conductivity of semiconductor zinc oxide radicals and how to prepare zinc oxide-based nanocrystals with controllable morphology has been a problem that has plagued scientific researchers in various countries.
