摘要
航天器在高真空环境运行时,所用非金属材料释放的有机分子污染物易沉积在航天器敏感部件表面,严重影响航天器的性能和使用寿命。沸石分子筛材料含有丰富孔道结构,具有独特的分子吸附特性,可用于在轨分子污染物的吸附控制。文章详细综述了沸石分子筛材料在控制在轨分子污染物方面的应用与研究现状,分析国内外研究差距,并展望未来发展方向。
In the high-vacuum environment,the organic molecular contaminations released from the nonmetallic 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.
