Miscibility and Thermal Properties of Bacterial Poly(3-Hydroxybutyrate-co-3-hydroxyhexanoate)/Poly(Ethylene oxide) Blends

Article Preview

Abstract:

The miscibility and thermal properties of poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)/poly(ethylene oxide) blends were investigated by differential scanning calorimetry (DSC). The results indicated that PHBHHx showed complete miscibility with PEO for PHBHHx/PEO 95/5, 90/10 and 80/20 blends as evidenced by the single composition-dependent glass transition temperature and the depression of the melting temperature of PHBHHx. However, PHBHHx showed partial miscibility with PEO for the other three blends as shown by the existence of unchanged composition independent glass transition temperature. The incorporation of PEO may improve the performances of PHBHHx to meet the different need in biomedical applications.
