Abstract
The present invention relates to a high heat-resistant graphene oxide, a method of manufacturing conductive graphene fiber from the same, and conductive graphene fiber manufactured by the method. The technical gist of the present invention is to provide high heat-resistant graphene oxide not having an oxygen-containing functional group such as a lactol group or a carboxyl group on the surface but having an oxygen-containing functional group such as an epoxy group or a hydroxyl group on the surface, thereby exhibiting thermal resistance and stability. In addition, the technical gist is also to provide a method of manufacturing conductive graphene fiber from the high heat-resistant graphene oxide and conductive graphene fiber manufactured by the method.
