Thermal analysis technology is a method and technique of measuring the relationship between a certain physical property of a substance and temperature or time changes under programmed temperature control and a certain atmosphere.It is capable of measuring the changes in substances accurately and rapidly,and has important applications in the characterization of carbon nanomaterials.This paper briefly discusses the progress and results of the application of thermal analysis and its coupled techniques in the characterization of carbon nanomaterials.The results show that they provide practical research methods for the exploration of oxidation resistance,thermal stability,surface oxidation,different forms of carbon content,and thermal decomposition mechanisms of carbon nanomaterials.At the same time,combined with some of the author's work in this area,the specific application of thermal analysis technology is elaborated.Finally,the paper provides important outlook for the application of thermal analysis and its coupling techniques in the characterization of nanocarbon materials.
