The improved thermal oxidative stability of silicone rubber by using iron oxide and carbon nanotubes as thermal resistant additives
Source abstract
Abstract
Abstract To investigate the effects of crystalline forms of iron (III) oxide and the bound between γ-Fe 2 O 3 and carbon nanotubes (CNTs) on the thermal oxidative stability of silicone rubber, a series of silicone rubber based composites filled with CNTs, α-Fe 2 O 3 , γ-Fe 2 O 3 , a mixture of γ-Fe 2 O 3 and CNTs, and γ-Fe 2 O 3 modified CNTs (γ-Fe 2 O 3 − CNTs) were prepared, respectively. Characterizations of the additives and the composites were performed by transmission electron microscopy (TEM), X-ray diffraction (XRD), Raman spectroscopy, thermogravimetric analysis (TGA), and X-ray photoelectron spectroscopy (XPS). The results indicated that the presence of CNTs affected the crystalline form of attaching Fe 2 O 3 which was changed from α to γ. γ-Fe 2 O 3 also got a enlarged special surface area in the γ-Fe 2 O 3 − CNTs. γ-Fe 2 O 3 was a more effective thermal resistant additive than α-Fe 2 O 3 due to the changes of crystalline form during the thermal aging. A synergy was found in the γ-Fe 2 O 3 − CNTs and much more changes of valence made γ-Fe 2 O 3 − CNTs as a more effective thermal resistant additive.
