Unformatted text preview: Ramanathan et al. reported that only 0.05 wt% treated graphite in polymethyl methacrylate (PMMA) offered an improvement of nearly 30 o C in glass transition temperature of the polymer (Ramanathan, et al. 2008). For fluoropolymer nanocomposites study, nanoclays have been used as reinforcing fillers most frequently. Nanoclay was found to affect vulcanization kinetics of a fluoroelastomer. It could effectively reduce the energy requirement for the curing process of the fluoroelastomer (Kader and Nah 2004) and increase the thermal degradation temperature of the fluoroelastomer in both nitrogen and oxygen atmospheres (Kader, et al. 2006). Meanwhile, M. Maiti, et al., pointed out the concentration of nanoclay in fluoroelastomer influenced dynamic mechanical properties of the composites and 20 wt% nanofiller provided the optimized storage modulus (Maiti and Bhowmick 2006)....
