摘　　要：掺杂不仅改变石墨块体材料的成分,还可以改变其微观形貌和微观结构,进而影响材料的力学性能、导热性能、导电性能和抗氧化性能。在总结石墨掺杂改性的方法和石墨掺杂改性原理的基础上,综述了目前国内外掺杂石墨材料的研究现状。Doping changes the phase compositions of graphite bulk materials as well as the micromorphology and microstructure,which are the grounds of influencing on the performance of the material mechanics,heat conduction,electrical conduction and oxidation resistance.The present research status of doped graphite materials at home and abroad is reviewed,which is based on the summary of methods and principles of doping vario-property for graphite materials.
