Atom oxygen (AO) can cause most spacecraft material erosion seriously. Liquid-exfoliated graphene by jet cavitation was used to coat Kapton employed on spacecraft to enhance its AO erosion resistance. The coating was prepared by vacuum filtering and transferring. After AO exposure, compared with naked Kapton, the mass loss of coated Kapton reduced to 3.73% and the erosion yield reduced to 3.67%. AO reacted with graphene and then was left in the coating. The coating was degenerated slightly, but still performed well. We believe that graphene coating could be potentially applied to increase the material's life span on spacecraft.
