| 英文摘要 | 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. |
