摘要

Materials used in low earth orbit are exposed to damaging atomic oxygen (AO). AO exposure behaviors of carbon nanotube (CNT) film and CNT/epoxy composite film were evaluated when exposed to a nominal AO fluence of about 3.0 × 1020 atoms/cm2. Properties of the films before and after AO exposure were evaluated by mass loss, Raman spectroscopy, X-ray photoelectron spectroscopy, tensile and electrical conductivity tests. Results show similar mass loss and different surface erosion for two kinds of films. CNT bundles collapse with the emergence of a tight arrangement of particles, and porous CNT film has more serious interior CNT erosion than dense CNT/epoxy composite film. Decreases of tensile strength and electrical conductivities are seen.
