▎ 摘　　要

NOVELTY - Preparing dispersible graphene nanocomposite particle comprises carrying out spray-dried granulation of aqueous dispersion containing metal salt and graphene oxide at 100-400 degrees C. USE - The nanocomposite particle is useful as antiwear and antifriction agent for lubricating oils (claimed). ADVANTAGE - The dispersible graphene nanocomposite particle has uniform particle size, excellent dispersion stability, and exhibits small friction coefficient and wear spot diameter. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for dispersible graphene nanocomposite particles obtained by above method.
