英文摘要： Due to excellent properties and the dual nature of structure and function, carbon/carbon(C/C) composites find more and more applications. The ongoing in-depth study of thermoelectric materials reveals new traits that indicate new potential applications. The study on the thermoelectric properties of C/C composites in the project will expand the understanding of the nature of C/C composites. Since heat and electricity can be converted reversibly by means of thermoelectric effects, thermoelectric materials are becoming new energy materials that have drawn extensive attention. In the project, analysis of thermoelectric transport and characterization of microstructures are carried out firstly. Secondly, carrier transport characteristics, microscopic scattering mechanisms and the coupling effect of C/C composites on carrier transport behavior are studied. In the end, the thermal and electrical transport characteristics are systematically recognized and the physical mechanisms of thermoelectric effect are understood. Thermoelectric properties can be evaluated based on these efforts. The research lays the foundation for the future potential applications and could provide new perspectives for the development of thermoelectric materials.
