Abstract:
In the high-vacuum environment, the organic molecular contaminations released from the non-metallic materials in spacecraft may easily be deposited on the surface of spacecraft sensitive parts, with adverse effects on the performance and the service life of the spacecraft. The zeolite molecular sieve, with a structure full of pores and unique adsorption properties, can be used for the adsorption control of the in-orbit molecular contamination. This paper reviews the field of the contamination concentration control, with a comparative analyses of the studies both at home and abroad. Suggestions are made for the future development of molecular adsorption coatings.
