Abstract

To prevent the migration of energetic plasticizers in propellants, Graphene oxide (GO) was added as filler to the ethylene propylene diene monomer (EPDM) insulation composite by mechanical mixing. Then, the anti-migration performance was analyzed by investigating the diffusion of dioctyl sebacate using immersion tests at different temperatures. The diffusion coefficient is in the range of 10–14-10–12 m2/s, and the migration activation energy is about 60 kJ/mol. Compared with pure EPDM, the anti-migration effects of EPDM/GO-5 are increased by 15.68%, 9.23%, 8.81%, and 5.69% at 25 °C, 40 °C, 60 °C, and 80 °C, respectively. Moreover, the composite shows a 58% increase in tensile strength and a 132% improvement in the elongation at break by the addition of 5 phr filler of GO. Meanwhile, the thermal stability of the EPDM insulation is also improved with the addition of GO.
