| Research Abstract |
A ground-based experiment was carried out in order to establish comprehensive understandings of the synergistic effect on the material degradation in a space environment. It was found that the collision-induced oxidative reaction is the major reaction pathway of the gasification reaction for hydrocarbons. The additional photon exposure accelerates desorption rate of reactive products, which is the rate-limiting process of mass-loss. In contrast, both collision-induced and photo-induced main chain scissions occur during the simultaneous exposure conditions of atomic oxygen and ultraviolet, however these reactions are parallel reactions such that synergistic effect is not observed.
