Abstract
Filled fluorosilicone and filled fluorophosphazene composite films and unfilled fluorosilicone, fluorophosphazene, or copolymers provide atomic oxygen resistance to protect surfaces on spacecraft in low earth orbit. The preferred composite films are generally made by polymerizing suitable precursors on the exposed surfaces, the filler being mixed with the polymer precursors prior to curing. Second surface mirrors can be protected with these films while the flexibility of the mirror is retained.
