【Abstract】 Graphene is one of the most widely known carbon materials owing to its excellent thermal and electrical properties. It has significant potential for application in thermal conductivity. Graphene-modified thermo-conductive composites(GTCCs), fabricated using graphene and a polymer, have excellent mechanical and thermal properties, and chemical stability. GTCCs is an effective solution for the heating issues commonly experienced by electronic equipment, with the potential to replace commercial thermally-conductive silicone grease. Combining the fundamental concepts derived from GTCC-related research and refining the key information will facilitate the practical development and promote the large-scale industrial application of the technology. In this review, the heat dissipation requirements of modern electronic equipment and the heat conduction mechanism of GTCCs are briefly examined. Subsequently, the modification methods of GTCCs are divided into three categories: filler hybrids, filler modification, and active fabrication of heat-conductive skeletons. The adaption of the production process to various modification methods and the local and international research progress are introduced. The practical applications of GTCCs in sensors and coatings are presented, demonstrating its significant industrial importance. Finally, the existing problems facing GTCC research are discussed, while summarizing and predicting the future prospects of the GTCC technology, concluding with guidelines for some promising developments.更多还原
