Effect of Organoclay on Thermal Degradation and Crystalline Morphology Properties of Biodegradable PHBV

Article Preview

Abstract:

Poly (3-hydroxybutyrate-co-3-hydroxyvalerate)/organoclay blends were prepared by solution blend method. The effect of organoclay on the thermal degradation and crystalline morphology properties were studied by thermogravimetry (TG)X-ray diffraction (XRD) and polarizing optical microscopy (POM) analyses. TG results indicates better processability of the blends with 5wt% organoclay than that of pure PHBV. XRD results show that the organoclay does not modify the crystal structure in the blends but only increase the intensity of diffraction peak. PHBV and PHBV/organoclay revealed integrated Maltese crossed spherulitic morphologies. While small-sized PHBV spherulites were formed when organoclay added to PHBV.
