▎ 摘　　要

NOVELTY - The structure has a functional component (3) partially impacted by an outflow (7) of an electric propulsion system. A graphene coating (9) is provided upon the functional component. The graphene coating overcoats a charge control coating upon the functional component. The charge control coating comprises indium tin oxide or a metal film. A portion of exhaust source points is directed such that outflow from the exhaust source points partially impacts the functional component. The graphene coating comprises a set of graphene flakes. USE - Spacecraft structure i.e. satellite. ADVANTAGE - The structure ensures that electrical conductivity of graphene can help protect sensitive components of a spacecraft structure against electrostatic discharge. The graphene coating can protect a surface of a spacecraft structure by decreasing sputtering and providing electrostatic discharge protection, or protect the protective coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for operating spacecraft structures. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a spacecraft structure incorporating an electric propulsion system and a functional component with a graphene coating.
