▎ 摘　　要

NOVELTY - Manufacture of graphene material-metal nanocomposite involves forming a layer of graphene material and/or a graphene precursor material on at least a portion of surface of surfaces of metal nanowire, and calcining metal nanowire comprising layer of graphene-precursor material. USE - Manufacture of graphene material metal nanocomposite used for forming electronic device such as electrical motor, electrical generator, transformer, switching regulator, converters, inverters, charging circuits, discharge circuits, printer control language control device, transmission units, distribution units, battery device, battery power management device, consumer electronic device, home appliance device, solar cell, wireless sensor device, control device, amplifiers, attenuators, internet of things devices, battery charging device, battery power management device, an audio device, radiofrequency identification reader device, and illuminating device (all claimed). ADVANTAGE - The method provides graphene material-metal nanocomposite having excellent electrical conductivity and thermal conducting performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) nanocomposite, which comprises a metal core and the graphene material layer placed on at least a portion or all the surface of the metal core; (2) formation of conductive element of an electronic device; and (3) manufacture of article.
