This article has been updated


In the space environment, spacecraft on orbit released a series of organic gas molecules by means of material outgassing, vacuum outgassing, eliminating propellant, and so on. These gas molecules can deposit on sensitive surface by direct transportation, reflection, atmospheric-scattering transportation, self-scattering transportation, and thermalization atmospheric-scattering transportation, such as optical elements, thermal control coating, and solar cell, which can result in decrease of the property even out of work. Contamination control was the trend of long-life and high-reliability spacecraft. As a new type of contamination control technology, molecular adsorber based on ceramics with convenient measuring, lightweight, low power consumption is a useful way of controlling contamination of spacecraft-sensitive device. There is not any study on molecular adsorber, although the molecular contamination test and simulation analysis have been researched by many people in China. This article analyses the adsorption mechanism study of porous material to organic molecular contamination in vacuum and studies the adsorption property study of porous material to organ-molecular contamination in vacuum. Through the method study of molecular adsorber absorption capability, the development of molecular adsorber is suggested.
