Abstract
To effectively dissipate heat discharged from various electronic or mechanical components, a high-performance ultra-thin heat dissipation sheet with high thermal conductivity and thermal emissivity by using a graphene/graphite nanoplate/carbon nanotube/nano-metal complex that forms a high-content 3D-structured complex that is stably dispersed, and a method of manufacturing the same, is provided. The method includes preparing a first heat dissipation film by sintering a composition for dissipating heat including a graphene/graphite nanoplate/carbon nanotube/nano-metal complex dispersion solution and a binder, and forming a second heat dissipation film on one surface or two opposite surfaces of the first heat dissipation film by using a graphene adhesive including the graphene/graphite nanoplate/carbon nanotube/nano-metal complex dispersion solution and an adhesive. A heat dissipation sheet according to the present invention may be utilized as a material with heat dissipation properties constituting a heat sink alone or with other materials with heat dissipation properties.
