Protection of Kapton from Atomic-Oxygen Erosion Using a Polysilazane Coating

Abstract:

The polysilazane synthesized by aminolysis of dichloromethylviny was coated on kapton by dip-coating method, the AO exposure tests was carried out in a ground-based AO simulator. It is found that the erosion yield of kapton was decreases by about two orders of magnitude. After exposure the coated katpon still have a smooth surface, and its optical properties are still at a high level. The polysilazane coating exhibits a superior AO erosion resistance.
