Abstract
Summary Coatings on Kapton film have been developed to provide resistance to atomic oxygen attack in a low Earth orbit environment. This material is to be used as the flexible substrate of the solar array panels on the Space Station Platform; and it must be both atomic oxygen resistant and sufficiently flexible to withstand solar array manufacture and deployment. Several candidate coatings and deposition processes were investigated, including sputtered SiO2, SiO2-fluoropolymer mixtures and indium-tin oxide. Results are presented to show the different failure modes of these coatings. SiO2 coatings were chosen for scaleup to manufacture, and initial results of this phase are presented.
