/ method for manufacturing a heat sink with stacked multilayer of Graphene/CNT complex thin film and a heat sink manufactured by the same method

摘要

The present invention relates to a method of manufacturing a heat sink having multiple layers of a graphene / carbon nanotube composite thin film laminated thereon and a heat sink manufactured by the method. More particularly, the present invention relates to a method of manufacturing a heat sink by oxidizing a surface of a heat sink by oxidizing the heat sink. (2) preparing a carbon nanotube dispersion solution surface-modified with an amine group or an amide group; (3) depositing a surface-modified carbon nanotube thin film on the heat dissipation plate by dipping the heat dissipation plate into the carbon nanotube dispersion solution; (4) depositing graphene oxide on the carbon nanotube thin film by dipping the heat sink through the step (3) into a graphene oxide dispersion solution to form a graphen oxide / carbon nanotube composite thin film on the heat sink; And (5) repeating the steps (3) and (4) in this order to form a multi-layered graphene oxide / carbon nanotube composite thin film. / Carbon nanotube composite thin film.;
