Title:
HEAT-RADIATING SHEET USING GRAPHENE/GRAPHITE NANOPLATE/CARBON NANOTUBE/NANOMETAL COMPLEX, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/012427
Kind Code:
A1
Abstract:
The present invention relates to an ultrathin heat-radiating sheet having excellent performance with high thermal conductivity and thermal emissivity, using a graphene/graphite nanoplate/carbon nanotube/nanometal complex forming a complex of 3D structure that is stably dispersed in high content, and a manufacturing method therefor, the ultrathin heat-radiating sheet being for effectively radiating heat emitted from various electronic or mechanical components, for example, an LED device, a chip of an electronic circuit, a wiring, a car engine, a radiator, a battery, a heating-cooling radiator, a CPU, etc. The present invention provides a manufacturing method for a heat-radiating sheet, comprising the steps of: manufacturing a first heat-radiating film by sintering a heat-radiating composition comprising a dispersion of graphene/graphite nanoplate/carbon nanotube/nanometal complex and a binder; and forming a second heat-radiating film on one or both sides of the first heat-radiating film using a graphene adhesive material comprising a dispersion of graphene/graphite nanoplate/carbon nanotube/nanometal complex and an adhesive. The heat-radiating sheet of the present invention can be used as a heat-radiating material forming a heat radiator, either alone or in combination with other materials having heat-radiating properties.
