Polyimide (PI) composite films are widely used on the external surfaces of spacecraft to protect them from the adverse environments of low Earth orbit (LEO) due to their outstanding comprehensive performance. However, current PI composite films have inadequate mechanical properties and atomic oxygen (AO) resistance.
