The objective of this thesis is to investigate the mechanical and thermal properties of blend between PBS and PHBV, and PBSA and PHBV.
PHBV is a family of polyhydroxyalkanoates, which are fully biobased and biodegradable polymers. However, is a brittle plastic with a high modulus value, low elongation at break, and poor thermal resistance, limiting its widespread applications. For this reason PHBV can be blended with several other polymers to improve its properties. On the other hand, PBS and PBSA are biodegradable polyester, softer material with a relatively low modulus and a higher elongation at break and thermal stability.
Therefore, the blending of PBS/PBSA and PHBV offers us the possibility of combining the advantages of these polymers while simultaneously mitigating their less desirable properties.
After these preliminary tests, the processability of the blends have been investigated with flat sheet extrusion and blown film extrusion, to understand the possible applications of the blends.
