Mechanical Properties and Flame Retardancy of Epoxy Resin/Nanoclay/Multiwalled Carbon Nanotube Nanocomposites

Figure 5

XRD patterns for I.30E: nanoclay (MMT), EP4: nanocomposite of epoxy resin with 2 wt.% MMT/0.01 wt.%, EP5: nanocomposite of epoxy resin with 2 wt.% MMT/0.02 wt.%, EP6: nanocomposite of epoxy resin with 2 wt.% MMT/0.03 wt.%; nanoclay (MMT) shows a basal reflection at 4.1° (d-spacing = 6.4 nm) corresponding to [0 0 1] plane. It also shows another peak at 20.1°. The nanocomposites with 1, 2.5, and 5 wt.% clay exhibit no Braggs scattering, indicating that silicate layers of organoclay may be exfoliated as they do not have any regular repeating distance.
