Preparation Technology of Graphene-Modified Carbon Materials

Graphene-modified carbon materials is the frontier hotspot research direction in the field of carbon-graphite materials. The research team of special carbon materials in the School of Materials Science and Engineering, Northwestern Polytechnical University aims to meet the major needs of aerospace, new energy, environmental protection, transportation engineering, etc., and is guided by demand, mainly focusing on the exploration and research on graphene/carbon nanotube composites, graphene/pitch based carbon foam composites, graphene modified pitch, carbonization and graphitization of graphene modified resin, graphene fibers and their composites, as well as the engineering applications of graphene and its composites. Through the selection and composition control of raw materials, improvement of preparation processes, structure-activity relationship between material structure and performance, optimization and iteration of theoretical models and experimental results, graphene and its carbon based composites with excellent properties such as thermal conductivity, conductivity, high strength, electromagnetic shielding, absorption, and adsorption have been prepared, and have been preliminarily applied in aerospace, energy, environmental protection, road engineering, and related fields. It is expected to be further applied in other high-performance carbon graphite materials.
