Enhancement of thermal conductivity of aluminium by doping graphene followed by melting and casting process

Process for preparation of high thermal conducting aluminium graphene or reduced graphene oxide composite materials, through melting, and casting process by doping of graphene or reduced graphene oxide into aluminium metal of any form, the process comprises the steps of:

• i) doping of graphene or reduced graphene oxide nano to micro size around aluminium metal and charging to a controlled furnace under argon surrounding atmosphere of the charge inside the furnace at 700 to 900 deg C. to melt the mass with or without salt and flux NaF;
• ii) casting the molten mass into any prefabricated shaped and sized die or mould cavity either in inert or in vacuumed or atmospheric pressured condition using salt and flux.
• iii) cooling the temperature back to room temperature and preparing the cast composite materials to prepare the product;
• wherein the weight of salts is 25% to 35% of total weight of the aluminium and graphene or reduced graphene oxide charge.
