Therefore, both of the morphologies can be achieved. Comparing the TEM micrographs of Fig. 3a, b reveals that the extent of exfoliation of Cloisite 15A nanoparticles in the compatibilized PP-rich blend is greater than that for non-compatibilized one. Similarly, Fig. 3 shows that the exfoliation of Cloisite 30B in the PLA-rich system is greater in the presence of the PTW compatibilizer (Fig. 3d) as compare to non-compatibilized nanocomposite (Fig. 3c).
