Figure 5b shows the WAXS patterns of pure Cloisite 30B, and PLA-rich blend containing 5 mass% of Cloisite 30B without compatibilizer and that with compatibilizer. As clearly seen, the characteristic peak of Cloisite 30B, at 2h of 4.7, has been shifted significantly to a lower angle in the compatibilized and non compatibilized PLA-rich blends.
