17 There are also many studies on thermoplastic elastomer. It has been shown that many TPEs, e.g., diene rubber/polyolefin blend-based thermoplastic elastomer (Fischer 1985), butyl rubber/polypropylene blend-based thermoplastic elastomer (Liao, et al. 1994), and acrylic rubber/poly(vinylidene fluoride) blend-based thermoplastic elastomer (Li, et al. 2006), show higher mechanical properties, such as tensile strength, tensile modulus and storage modulus, through dynamic vulcanization. 1.6.2 Objectives Nanofillers such as nanoclays, silica nanoparticles, and functionalized graphene sheets have been reported to improve mechanical and thermal properties of the polymer matrixes, which are mainly traditional non-fluoropolymers such as PMMA, PU, and PVAc, etc. To the best of our knowledge, little research has been done on the effects of nanofillers (e.g., treated silica and functionalized graphene) on mechanical and physical

Unformatted text preview: properties of the high-performance fluoroelastomers. This is especially true for fluoropolymer/graphene nanocomposites. No studies and results can be found on this type of nanocomposites in the open literature. On the other hand, though many studies of TPEs have been carried out, the influence of nanofillers on mechanical and thermal properties of high performance TPE systems, i.e., fluorothermoplastic elastomer (F-TPE), still needs to be further investigated. Further, the effects of nanofillers on dynamic vulcanization of F-TPE and on morphology of the resulting F-TPE nanocomposites also deserve an in-depth investigation. In this study, different types of nanofillers were employed to reinforce the fluoroelastomer. Their effects of the nanofillers on curing kinetics, mechanical and...
