▎ 摘  要

NOVELTY - Thermally conductive three-dimensional (3D) graphene-polymer composite material comprises (a1) a porous 3D graphene structure (100) comprising a network of graphene layers (102) that are attached to one another through a carbonized organic polymer bridging agent (104) and (b1) a polymer material impregnated within the porous 3-D graphene structure. USE - The composite material is useful in manufacturing article comprising electronic device comprising light emitting diode light, a notebook, a mobile phone, or mobile computing device (smart phones, tablets or laptops) (all claimed), electrowetting display device including transistor, a resistor, a logic device, sensors, antennas, integrated circuits, electroluminescence devices, memory elements or a field effect device. ADVANTAGE - The thermally conductive 3D graphene-polymer composite material has a thermal conductivity of 1-16.7 W/mK at 25-90 degrees C, preferably 10-16 W/mK at 25-90 degrees C, super conductivity, and high surface area. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for making the thermally conductive 3D graphene-polymer composite material comprising (a) obtaining a dispersion of graphene layers and an organic carbon containing polymer in a solvent, (b) drying the dispersion to obtain porous 3D graphene structure comprising a network of graphene layers and the organic carbon containing polymer, (c) annealing the porous 3D graphene structure from step (b) to carbonize the organic carbon containing polymer such that the graphene layers are attached to one another through the carbonized organic carbon containing polymer, (d) combining the annealed porous 3D graphene structure from step (c) with a solution comprising a thermoset or thermoplastic material under conditions to allow the solution to infiltrate the pores of and impregnate the annealed porous 3D graphene structure and (e) curing or drying the impregnated annealed porous 3D graphene structure to obtain the thermally conductive 3D graphene-polymer composite material.
