5 less attention has been paid to rubber/clay nanocomposites, especially some specialty elastomers, such as fluoroelastomers. Depending on compounding methods and the interfacial interactions between nanoclay and elastomer matrix, three main types of morphologies of elastomer-clay composites can be produced as shown in Figure 1.2 (Koo 2006): (a) Unintercalated: the regular layered structure (stack) of originally modified nanoclay is not disrupted, and nanoclay is dispersed like a regular particulate filler.

Unformatted text preview: (b) Intercalated: this state is formed by the insertion of rubber chains between the nanoclay layers, the ordered structure of layers is retained. . (c) Exfoliated: In this state, individual layers of the nanoclay are completely delaminated and dispersed in the rubber matrix. The ordered structure of the layered nanoclay is lost.
