“…AO is one of the major space environmental hazards faced by spacecraft operating in the LEO environment for a long duration. Because of its high chemical reactivity and high impeding energy, AO attacks can cause severe surface degradation of polymeric materials for space, which can have a serious influence on spacecraft performance. , However, in addition to the AO, a spacecraft in low Earth orbit (LEO) will encounter vacuum-ultraviolet (VUV) radiation. Although the VUV irradiation energy accounts for a very small portion of the total solar irradiation energy, it has a significant impact.…”

A flexible, dense, defect-free, highly adhesive, and highly dissociation energy-rich protective coating is essential to enhance the atomic oxygen (AO) resistance of polymeric materials in a low Earth orbit (LEO). In this work, a dense, defect-free hybrid HMDSO/SiO 2 thin film coating with compositional gradients on the surface of polyimide was synthesized using vacuum-ultraviolet (VUV) irradiation. The effects of VUV irradiation on the morphology, optical transmittance, and chemical components of plasma-polymerized HMDSO (pp-HMDSO) thin-film coatings deposited on the polyimide surface were investigated in depth. There were no defects such as cracks and holes in the surface morphology of pp-HMDSO films after VUV irradiation, but the surface roughness increased slightly, and the corresponding optical transmittance decreased slightly. The chemical components of pp-HMDSO films were changed in the depth direction starting from the top of the surface, forming hybrid HMDSO/SiO 2 thin films with compositional gradients. The component gradient HMDSO/SiO 2 composite coating further enhanced the atomic oxygen resistance of the polyimide due to the surface layer of the UV-modified coating enriched with high dissociation energy SiO x material. Therefore, this work provides a facile UV-induced synthesis method to prepare dense, defect-free, and highly dissociation energy-rich protective gradient coatings, which are promising not only for excellent AO protection in LEO but also for potential application in water−oxygen barrier films.
