▎ 摘 要
NOVELTY - Producing a metal modified honeycomb graphene-copper composite particle involves mixing copper nitrate, aluminum hydroxide colloid, and graphene powder into deionized water, and ultrasonically dispersing it uniformly to obtain a dispersion. The method involves adding dispersion to a freezing device, quenching it by liquid nitrogen, taking it out and then freeze-drying to obtain a microporous composite containing graphene. The method involves pulverizing microporous composite into a granular structure, uniformly paving it into reaction kettle, and reducing metal copper by introducing a vapor to obtain a composite particle. The obtained composite particle is subjected to acid cleaning, collected by low-speed centrifugation, washed with water, and dried to obtain final product. USE - Method for producing metal modified honeycomb graphene-copper composite particle used in fields where mechanical properties and thermal conductivity of metal materials are strictly required. ADVANTAGE - The method enables to produce metal modified honeycomb graphene-copper composite particle, which effectively realizes uniform dispersion of graphene in metal, does not agglomerate easily, imparts high strength and lightness to metal material, and forms relatively perfect heat conduction network, which improves thermal conductivity of material.
