3 compounds, causing the end products to weigh significantly more than the neat rubber. In the last few decades, the concept of nanocomposites has shown great potential to alleviate the problem of high loading of particulate fillers in the elastomeric matrix. Nanocomposites give manifold increase in useful properties by dispersing small amount of nano scale filler such as layered silicate (clay) in the polymer matrix. However, to achieve good dispersion, the layers of the silicate should undergo intercalation and exfoliation (delamination) in the polymer matrix. 1.2 Thermoplastic Elastomer and Fluorothermoplastic Elastomer Thermoplastic elastomers (TPE) have been attracted much attentions since 1950s, when they became a commercial reality. TPE, sometimes referred as thermoplastic rubbers, are a class of copolymers or a physical mix of a plastic and a elastomer which consist of materials with both thermoplastic and elastomeric properties. In this study,

Unformatted text preview: fluorothermoplastic elastomer (F-TPE) is defined as a specific TPE which contains fluorothermoplastic and fluoroelastomer. Generally, these types of materials show the following advantages: (1) both advantages typical of rubbery materials and plastic materials, (2) processable and recyclable like thermoplastic, (3) great improvement of properties achieved by the addition of small amount of nanofillers. While the advantages of F-TPE lead to extensive applications, the limitations are also obvious: high cost of raw materials, insufficient mechanical and thermal stability which might not be enough for certain uses. To overcome these disadvantages, different nanofillers can be used to improve the F-TPE’s properties. Detailed information, experiments and results will be introduced in the following chapters....
