摘要: To investigate the synergistic effect and mechanism of γ-Fe2O3 modified carbon nanotubes (γ-Fe2O3–CNTs) on thermal stability silicone rubber (SR) under different atmospheres, a series SR-based composites added with α-Fe2O3, γ-Fe2O3, CNTs γ-Fe2O3–CNTs were prepared subsequently investigated by Raman spectra, X-ray diffraction, thermogravimetric analysis tensile testing before after aging swelling experiment. The results exhibited that had significant SR both nitrogen air atmosphere. Under atmosphere, depolymerization was delayed greatly in whole temperature range. For example, T 50 (the at which 50 % degradation occurs) γ-Fe2O3–CNTs/SR 56.9 °C higher than neat SR. is attributed to nice combination conductivity relatively low-temperature range enhanced interfacial reaction high-temperature initial improved about 50 °C. mainly proposed include can promote each other capture free radicals thereby terminate thermo-oxidative process significantly. Owing excellent antioxidant ability γ-Fe2O3–CNTs, its composite changed completely.
