Review on Protective Thin Films for Space Environments in Spacecraft Applications

The complicated and particular space environment poses the serious threaten to the service life and performance of spacecraft.Enhancing the resistance to space environment for spacecraft surface material has always been a key question of spatial technology development.At present,the surface thin film technology has been widely applied in the protections of spacecraft thermal coating,optical device and so on.This article in view of the effect on spacecraft surface materials in the atomic oxygen environment,the plasma environment,and the space pollution environment,discussed the development of the relative protective thin films and the main preparation method briefly.On the basis of the date from the ground space simulation experiments and flight tests,analyzed the space environment compatibility of these protective thin films,and summarized the overall performance which the space environment protective thin films should process,and proposed the content of future development in space thin films will be the complicated films and the system of criteria for protective thin films of spacecraft.
