▎ 摘　　要

NOVELTY - Graphene-containing vanadium dioxide composite powder comprises core-shell particles and graphene dispersed between the core-shell particles. The core-shell particles include vanadium dioxide particles and metal. The metal coating forms a metal shell on the surface of the vanadium dioxide particles. The mass ratio of the vanadium dioxide particles, the metal and the graphene is 70-98:1-20:1-10. USE - The powder is useful for preparing vanadium dioxide composite coating (claimed). ADVANTAGE - The powder reduces the permeation and absorption of infrared ray and saves energy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene-containing vanadium dioxide composite powder, comprising dispersing the graphene in the metal salt solution, dispersing the vanadium dioxide particles in a metal salt solution to obtain mixture, adding pH adjuster, stabilizer, complexing agent and reducing agent into the mixture to obtain reaction solution, subjecting the metal salt into reduction reaction to obtain metal shell on the surface of the vanadium dioxide particles, centrifuging the reaction solution, washing and drying.
