Abstract
The present disclosure relates to the field of new materials, and aims at providing an A-site high-entropy nanometer metal oxide with high conductivity, and a preparation method thereof. The metal oxide has molecular formula of Gd0.4Er0.3La0.4Nd0.5Y0.4)(Zr0.7, Sn0.8, V0.5)O7 and is a powder, and has microstructure of the metal oxide as a square namometer sheet with a side length of 4-12 nm and a thickness of 1-3 nm. Compared with an existing high-entropy oxide, the product in the present disclosure has high conductivity, and can be well applied to a conductive alloy, an electrical contact composite material, a conductive composite material, a multifunctional bio-based composite material, a conductive/antistatic composite coating and the like.
