Title:
HIGH HEAT RADIATION GRAPHENE-POLYIMIDE COMPOSITE FILM HAVING INSULATION ABILITY, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/044085
Kind Code:
A1
Abstract:
The present invention relates to a graphene-polyimide composite film comprising multilayer graphene particles, and a manufacturing method therefor, and the method for manufacturing a graphene-polyimide composite film can express high thermal conductivity characteristics of graphene while maintaining an insulation characteristic of a polyimide and can manufacture a high heat radiation graphene-polyimide composite film having shielding characteristics with a light transmittance close to 0%. In addition, a precipitation phenomenon can be improved by increasing the dispersibility of materials when manufacturing the composite film by the manufacturing method. Therefore, the graphene-polyimide composite film of the present invention has excellent insulation, heat radiation, and shielding, thereby being useful in the field of electronic materials such as a heat resistant coating agent, an insulating film, a semiconductor, and an electrode protective film.
