説明

The synergistic effect of atomic oxygen and ultraviolet rays on the spin-coated polyimide film is investigated. The X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy suggest that the formation of carbonyl group at the film surface occurs during atomic oxygen exposures. The mass loss of the polyimide film and the enhancement carbon dioxide formation are observed during simultaneous irradiation of the low flux atomic oxygen and ultraviolet rays. These experimental results are explained by the photo-assisted chemical reaction of carbonyl groups formed by atomicoxygen attack. The fact that the synergistic effect of atomic oxygen and ultraviolet rays is obvious on the polyimide film, which is known as the material showing no synergistic effect in low Earth orbit, may reveal the importance of relative intensities of atomic oxygen and ultraviolet rays on the ground-based synergistic testing of the materials.
