The present patent of invention relates to aluminium-graphene nanocomposites with high electrical and thermal conductivity, and methods for obtaining same via microstructural control, and more specifically to the incorporation of multilayer graphene nanoplatelets (mGNP or few-layer graphene), comprising up to 10 layers, into pure commercial aluminium or aluminium alloys, using electric furnaces. The nanocomposites obtained comprise an aluminium matrix with dispersed graphene as the reinforcing phase, in proportions ranging from 0.1 wt% to 3 wt%. In order to obtain the nanocomposites, gravity casting techniques were employed in resistive and induction furnaces, with adaptations to prevent oxidation through the use of an inert gas atmosphere. The methodology employed enables a significant increase in electrical conductivity, ranging from 45% to 95% relative to the as-received commercial material, depending on the amount of graphene added. The thermal diffusivity of the nanocomposites also increased by 15% to 50%, with a possible maximum of around 0.5 wt% to 1 wt% of graphene. Similarly, the general physical properties exhibited marked improvements, although the rate of improvement decreased for nanocomposites containing more than 2 wt% of graphene.
