Perfluoropolyether (PFPE) lubricants play a significant role in the aerospace industry due to their outstanding chemical stability, thermal stability and anti-wear properties, however, their decomposition behavior has not been revealed fully. Herein, the decomposition mechanism and performance characteristics of four types of PFPE lubricants are investigated thoroughly by means of in situ heating fourier-transform infrared spectroscopy (in situ FTIR) and pyrolysis-gas chromatography/mass spectrometry (Py-GCMS). The results show that the …
