Unformatted text preview: particles. The two most widely used reinforcing fillers in the rubber industry are carbon black and clay. For example, Heinrich and Vilgis (1993) reported that carbon black showed an influence on crosslinking of polybutadiene and significantly increased its shear modulus. Also, fully exfoliated clay in epoxy matrix improved the storage modulus apparently (Park and Jana 2003). In order to achieve maximum reinforcement, the loading of these fillers should be appreciably high, which often creates processing problems. However, if the size of the fillers is in nano scale, the introduction of these nano-sized (e.g. nanoclay, nanosilica, etc.) fillers can result in polymer nanocomposites exhibiting multifunctional, high-performance characteristics beyond what traditional filled polymeric materials possess. Although layered silicate nanocomposites have been prepared and characterized for many thermoplastic and thermosetting polymers, much...
