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

Figure 4

TEM images of PMMA-grafted natural rubber toughened epoxy showing (a) rubber particles located outside the co-continuous phase. (b) and (c) Rubber contains occluded epoxy phase. (d) Nanorubber particles, with about 40 nm interparticle distance. The estimated sizes of rubber particles are (i) 9.24, (ii) 8.63, (iii) 8.01, (iv) 8.01, (v) 9.24, (vi) 9.24, and (vii) 7.39 nm.
