Morphological Study on Room-Temperature-Cured PMMA-Grafted Natural Rubber-Toughened Epoxy/Layered Silicate Nanocomposite

Figure 8

SEM images show the fracture surface of cured samples. (a) Neat epoxy. (b) Epoxy containing 5 phr MG 30. (c) Pores or cavitation on the rubber particles. (d) Epoxy containing 5 phr Cloisite 30B. (e)-(f) Epoxy containing 5 phr MG30 and 5 phr Cloisite 30B.
