Preparation and Atomic Oxygen Resistance of Polyimide/lnorganic Oxide Hybrid Composite Films
Three series of polyimide/ oxide nano composite films were synthesized through sol-gel method using zirconium n-butoxide, tetrabutyl titanate and tetraethyl orthosilicate as the oxide precursor, respectively. The atomic oxygen (AO) resistance testes of the films were carried out using a groundbased atomic oxygen effects simulation facility of Beihang University. The atomic oxygen fluence is about 3.1×1020 atom/cm2. The results indicated that the inorganic oxides-rich layer was formed on the polyimide film after AO exposure, which decreased the mass loss rate and obviously improved the AO resistance of polyimide films.
