摘　　要：采用傅里叶变换衰减全反射红外光谱技术(ATR-FTIR),研究了亚麻纤维的红外光谱(包括:一维红外光谱和二阶导数红外光谱)。实验发现:亚麻纤维主要存在着ν_(OH)、ν_(asCH_2)、ν_(sCH_2)、ν_(C=O)、ν_(H_2O)、δ_(CH)、δ_(OH)和ν_(C-O)等八种红外吸收模式。采用变温ATR-FTIR技术(包括:变温一维红外光谱和变温二阶导数红外光谱)进一步开展了亚麻纤维的热稳定性研究。研究发现:亚麻纤维的热稳定性较差,进一步研究了其热变机理。本项研究开拓了变温ATR-FTIR技术在亚麻纤维热稳定性的研究范围。The flax fiber was studied by fourier transform attenuated total reflection infrared spectroscopy（ATR-FTIR） including one-dimensional infrared spectroscopy and derivative infrared spectroscopy. The results showed that eight infrared absorption modes such as ν（OH）、ν（asCH2）、ν（sCH2）、ν（C = O）、ν（H2 O）、δ（CH）、δ（OH） and ν（C-O） existed.The thermal stability of flax fiber was analyzed by adopting variable temperature ATR-FTIR technology（ including variable temperature one-dimensional infrared spectroscopy and variable temperature second derivative infrared spectroscopy）. The results revealed that the thermal stability of the flax fiber was relatively worse and the mechanism of thermal stability was further researched. The research field of variable temperature ATR-FTIR in the analysis of thermal stability of the flax fiber was explored.
