Several kinds of polymeric nano-composites were fabricated by including different typologies of nano-size fillers into a commercial epoxy matrix. The employed additives are: multi-walled carbon nanotubes (MWCNTs), alumina (AL2O3) nanoparticles, and three types of graphene platelets (G-CD270, G-33C and G-24N). The effect of the exposition to low earth orbit (LEO) space threats on the candidate nano-composite materials were analyzed by characterization in ultra-high vacuum (~ 5 × 10–5 Torr), and atomic oxygen (AO) environment (fluence ~ 1.5 × 1021 AO/cm2) in the presence of vacuum ultra-violet (VUV) radiation (intensity peaked at 410 mW/cm2). About outgassing, parameters as total mass loss (TML), collected volatile condensable materials (CVCM), and water vapor regained (WVR) were measured. Furthermore, the mass loss and erosion rate due to the exposure to the synergic effects of AO and VUV were evaluated. Finally, the various specimens were studied by Fourier transmission infra-red spectroscopy (FTIR). The experimental findings assess the effectiveness of the proposed nano-composites for aerospace applications.
