Preparation and characterization of Polyhydroxyalkanoates (PHA) and Polylactide (PLA) blends

Abstract : Polylactide (PLA) and poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) blends were prepared in different compositions by melt mixing. The miscibility of the two components was first characterized by differential scanning calorimetry (DSC) experiments, which showed the immiscibility of the components for all blend compositions. The morphology was studied using scanning electron microscope (SEM) and optical microscopy in reflection. Nodular and co-continuous morphologies were observed depending on the composition. The rheology of the pure polymers and of the PLA/PHBV blends was investigated in the dynamic mode. The results showed a significant role of the interfaces with an increase of the complex viscosity at small frequencies.
