A thermally conductive three-dimensional (3-D) graphene-polymer composite material, methods of making, and uses thereof are described. The thermally conductive three- dimensional (3-D) graphene-polymer composite material contains: (a) a porous 3-D graphene structure comprising a network of graphene layers that are attached to one another through a carbonized organic polymer bridging agent; and (b) a polymer material impregnated within the porous 3-D graphene structure, wherein the thermally conductive 3-D graphene-polymer composite material has a thermal conductivity of 10 W/m.K to 16 W/m.K. L'invention concerne un matériau composite polymère-graphène tridimensionnel (3-D) thermoconducteur, ses procédés de fabrication et ses utilisations. Le matériau composite polymère-graphène tridimensionnel (3-D) thermoconducteur contient : (a) une structure de graphène 3-D poreuse comprenant un réseau de couches de graphène qui sont attachées les unes aux autres par l'intermédiaire d'un agent de pontage polymère organique carbonisé ; et (b) un matériau polymère imprégné à l'intérieur de la structure de graphène 3-D poreuse, le matériau composite polymère-graphène 3-D thermoconducteur ayant une conductivité thermique de 10 W/m.K à 16 W/m.K.
