- Abstract
Uniform spherical graphene/monocrystal-copper powder is fabricated by melting bulk laminated composite. Graphene, in the form of reduced graphene oxide (rGO), is uniformly dispersed on the surface of monocrystal Cu particle. A mechanism is proposed based on liquid/solid interface interaction combining the surface energy minimization of liquid Cu and low wettability of molten Cu on graphene. The rGO/Cu composite powder exhibits good sphericity, and the size distribution could be controlled by the amount of rGO.
