Abstract Polyimide or fluorine polymer that are used as heat-control materials on structures in LEO and GEO orbits, if not protected from the atomic oxygen (AO) may be severely degraded by the formation of microcracks. Carbonized materials are suitable for use in low Earth orbit (LEO) as they have excellent mechanical strength, electrical insulation, and thermal conductivity. Carbonized wood, in the form of a Japanese lacquer composed of aromatic compounds derived from the urushi tree, could potentially be used as the outer surface material of spacecraft, provided however that its resistance against AO irradiation in LEO is sufficient. The main aim of this study, therefore, is to develop the requisite technology to impart erosion resistance against AO to the carbonized wood. Specifically, increased sp2 bonding in the Si-doped diamond-like carbon introduced here is shown providing effective resistance against AO-induced erosion.
