▎ 摘  要

NOVELTY - A composite comprising graphene oxide and nanodiamond is manufactured by preparing a nanodiamond; attaching functional group on a surface of the nanodiamond by heat-treating the nanodiamond; dispersing nanodiamond comprising the functional group in a 1st solvent to prepare a nanodiamond dispersion; dispersing graphene oxide in a 2nd solvent to prepare graphene oxide dispersion; mixing graphene oxide dispersion and nanodiamond dispersion; and forming a bond between the graphene oxide and the nanodiamond. USE - Manufacture of composite comprising graphene oxide and nanodiamond for manufacturing nanofluid used in a vehicle and a thermal management system. ADVANTAGE - A nanofluid made using the composite comprising graphene oxide and nanodiamond has both dispersion stability and metal corrosion stability and has high thermal conductivity, where aggregation among the nanoparticles may be prevented, and two materials having high thermal conductivity are bonded, solving the characteristic deterioration problem.
