A graphite composition is provided. A graphite composition according to one embodiment of the present invention comprises: a graphite composite in which nanoparticles having a catecholamine layer on the surface thereof are fixed on graphite; and graphite of at least one of graphite flakes, spherical graphite, and expanded graphite. According to this, since the graphite composition has a high dispersibility in a substrate of a different material, a composite material thus realized exhibits a uniform heat dissipation performance and can prevent mechanical strength from deteriorating at a specific position. In addition, since the compatibility with the substrate of a different material is excellent and thus the interface property with the substrate is excellent, the realized composite material can exhibit a further improved heat dissipation performance and mechanical strength. Furthermore, it is very easy to form shapes during injection/extrusion molding in combination with a substrate, and molding into complicated shapes is also possible.
