Claims11
A heat spreader comprising:
- a copper substrate layer;
- and
- at least one layer of graphene deposited on the copper substrate layer, wherein the at least one layer of graphene comprises non-oxidised graphene and oxidised graphene, wherein the at least one layer of graphene includes thermally reduced graphene oxide, and wherein the at least one layer of graphene further comprises a top layer of silane-functionalised graphene.
A method of manufacturing a heat spreader, the method comprising:
- providing a copper substrate layer;
- and
- depositing at least one layer of graphene on the copper substrate layer, wherein the at least one layer of graphene comprises non-oxidised graphene and oxidised graphene, wherein the at least one layer of graphene includes thermally reduced graphene oxide, and wherein the at least one layer of graphene further comprises a top layer of silane-functionalised graphene.
