摘　　要：热分析联用分析技术包括同步联用技术、串级联用技术和间断联用技术,常见的有热重⁃差示扫描量热联用(TG⁃DSC)、热重⁃红外/质谱联用(TG⁃FTIR/MS)、固相原位热红外检测技术(Thermolysis/RSFTIR)和热重⁃红外⁃质谱联用(TG⁃FTIR⁃MS)等,是研究含能材料热行为和分解机理的有效方法,对研究其燃烧和爆炸性能有重要意义。相较于单一的热分析技术,联用技术可以更加充分、高效和全面地评价含能材料热行为和热安定特性、揭示热分解机制。通过热分析联用技术全面深入研究含能材料的物化特性,对改善和提高其应用性能具有重要的现实意义和价值。本文全面综述了TG⁃DSC、TG⁃MS、TG⁃FTIR⁃MS、TG⁃FTIR⁃GC⁃MS和Thermolysis/RSFTIR热分析联用技术在含能材料研究中的应用进展,分析了其研究的相关内容、重要结果、特点及优势,并进行了相关展望,可开发高性能的计算分析软件,解决如质谱分析中重叠质谱峰的解析等问题,在热分析仪中引入新的扩展系统,拓展其应用范围,为新型含能材料的热分析研究提供技术上的支持。Hyphenated techniques of thermal analysis,including common thermogravimetric⁃differential scanning calorimetry(TG⁃DSC),thermogravimetric⁃infrared/mass spectrometry(TG⁃FTIR/MS),Fourier transform infrared spectroscopy/solid⁃state in situ reaction techniques(Thermolysis/RSFTIR)and thermogravimetric⁃infrared⁃mass spectrometry(TG⁃FTIR⁃MS),are effective ways to study the thermal decomposition properties and mechanisms of energetic materials.Compared to the single thermal anal⁃ysis techniques,the hyphenated techniques of thermal analysis are more adequate,efficient and comprehensive ways to evalu⁃ate the thermal behaviors and thermal stability and to reveal the thermal decomposition mechanism of energetic materials.A comprehensive and in⁃depth study of the physicochemical properties of energetic materials by hyphenated techniques of thermal analysis is of great practical significance and value in improving and enhancing the performance of energetic materials in applica⁃tions.Herein,this paper presents a comprehensive review of the advance in the application of TG⁃DSC,TG⁃MS,TG⁃FTIR⁃MS,TG⁃FTIR⁃GC⁃MS and Thermolysis/RSFTIR hyphenated techniques in the study of energetic materials.The research contents,im⁃portant results,features and advantages of these techniques are analyzed,and related perspectives are presented,such as devel⁃oping high⁃performance computational analysis software,solving the problems such as the deconvolution of overlapping mass spectral peaks in mass spectral analysis,and introducing a new extension system in the thermal analyzer to expand the scope of their application,thus providing technical support for the thermal analysis of new energetic materials.
