摘要：

Organometallic compounds have been incorporated into organic polymers to improve their durability to the environment of the low earth orbit (LEO), particularly their resistance to erosion by atomic oxygen (AO). Bis(triphenyltin) oxide (BTO) was added to a thermoplastic polyetherimide, Ultem, and exposed on the Mir space station. The addition of the BTO to Ultem significantly reduced the mass loss in LEO. Aluminum acetylacetonate was added to a thermoset, PMDA-ODA polyimide. that is currently deployed on the International Space Station. Two films are placed in the ram direction exposed to AO and space radiation. Three films are placed in the wake direction and are exposed to space radiation but not AO. The doped films show superior resistance to AO. (C) 2003 Elsevier B.V. All rights reserved.
