| 英文摘要 | Effects of atomic oxygen (AO) irradiation on the structural and tribological behaviors of glass fiber (GF) and MoS2 filled polytetrafluoroethylene (PTFE) composites were investigated in a ground-based simulation facility, in which the average energy of AO was about 5 eV and the flux was 5.0 × 1015 cm–2 s–1. The structural changes were characterized by XPS and attenuated total-reflection Fourier transform infrared spectroscopy, and the tribological changes were evaluated by friction and wear tests and SEM analysis of the worn surfaces. It was found that AO irradiation induced the degradation of PTFE molecular chains, and the primary erosion mechanism is collisionally induced rather than chemically induced. The addition of MoS2 filler significantly increased the AO resistance of PTFE composites. Friction and wear tests indicated that GF and MoS2 improved the tribological properties of materials before and after AO irradiation. Short GF and MoS2 exhibited a good synergistic effect for improving the AO resistant and tribological properties of PTFE material. |
