摘要	Polysiloxane/SiO2 hybrid coatings have been prepared on Kapton films by a sol-gel process. The erosion resistance of polysiloxane/SiO2 (20 wt pct) coating was evaluated by exposure tests of vacuum ultraviolet radiation (VUV) and atomic oxygen beam (AO) in a ground-based simulation facility. The experimental results indicate that this coating exhibits better AO resistance than pure polysiloxane coating. The erosion yield (E-y) of the polysiloxane/SiO2 (20 wt pct) hybrid coating is about 10(-27) cm(3)/atom, being one or two orders of magnitude lower than that of polysiloxane. VUV radiation can affect the erosion process greatly. Under simultaneous AO and VUV exposure, the value of E-y of the polysiloxane/SiO2 (20 wt pct) hybrid coating increases by 39% compared with that under single AO exposure.
