In this study, a simple and cost effective method is developed for the production of graphene reinforced metal matrix composites and high surface area graphene foams. First graphene is grown on spherical copper powders via CVD. For graphene-metal nanocomposite formation the graphene coated copper powders are pressed. For free standing high surface area graphene foam formation the metal part is etched away. The obtained structures are characterized using SEM, Raman spectroscopy, XRD, EBSD and also their mechanical, thermal and electrical tests are performed. It is shown that this process is a very versatile method to produce both graphene-copper composites on a large scale, with a good dispersion and improved interface with the metal matrix and high surface area graphene foams. The porous structure can be further tailored by controlling the Cu powder size. (This study is supported by TUBITAK 1005 grant no 216M042.)
