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

Figure 7

TEM images PMMA-grafted, natural rubber-toughened epoxy layered silicate (Cloisite 30B) nanocomposite showing (a) silicates around a cavity, with estimated interparticle distances of (i) 3.49 and (ii) 3.17 nm; the distance between the cavity and a layered silicate is about (iii) 3.92 nm; (b) the estimated rubber particle sizes are (i) 8.36, (ii) 6.18, and (iii) 4.36 nm; (c and d) layered silicates are adsorbed on the rubber particles wall; (d) the estimated interlayer spacings are (i) 2.86, (ii) 2.87, and (iii) 3.37 nm.
