摘要

Different proportions of starch were blended with poly(β-hydroxybutyrate)-co-poly(β-hydroxyvalerate) (PHB-V) or poly(ε-caprolactone) (PCL) by extrusion and the mechanical properties (maximum tensile strength, elongation at break and Young's modulus) and thermal properties (DSC) were determined. The biodegradability of the blends in soil compostage was also assessed after thermal ageing for 192,425 and 600 h at different temperatures. The maximum tensile strength of the blend PCL50 (containing 50% starch) was 35% lower than that of PCL, and that of PHB-V50 was 60% lower than for PHB-V, without thermal ageing. PHB-V blends were more biodegradable than PCL blends. For of the blends prepared, thermal ageing affected the biodegradation only of blend PHB-V25.
