This paper analyzes the mechanism of the molecular adsorbers, which can be used to collect and remove the molecular contamination from spacecraft materials on-orbit. The selection method of the molecular adsorbents and the substrate, and the measurements of the adsorbing capacity and the effective sticking coefficient for the molecular adsorbers are discussed. A comparison between domestic and international studies is made and the development of the molecular adsorbers in China is suggested.
