Properties and improved space survivability of polyhedral oligomeric silsesquioxane (POSS) polyimides (PI) were investigated. It was found that the room temperature modulus of polyimide is unaffected by POSS, and the modulus at temperatures greater than the Tg of the polyimide is doubled by the incorporation of the 20 wt% POSS. To simulate lower earth orbit (LEO) conditions, POSS PI films underwent exposure to a hyperthermal oxygen atom beam. The films were characterized by X-ray photoelectron spectroscopy, atomic force microscopy and surface profilometry.
