Application of graphene on improving atomic oxygen resistance of material

The application of graphene on spacecrafts was proposed. Graphene was prepared by the ultrasonic cavitation method, then it was added into epoxy resin and nanocomposites were prepared by the mixing method. Results of thermogravimetric analysis show that the thermal stability of the nanocomposite is improved. The atomic oxygen effect experiments of pure epoxy resin and nanocomposites are conducted in a ground-based simulation facility. Results of mass loss, surface morphology and surface composition indicate that the atomic oxygen erosion resistance of nanocomposites is improved obviously.
