Abstract: Poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV) and shell powder are both biodegradable and biocompatible materials. PHBV/shell powder composites were prepared by the melt-blending method. Phase morphology, crystallization, thermal and mechanical properties of PHBV/shell powder composites were investigated by scanning electron microscope (SEM), polarizing optical microscope (POM), differential scanning calorimeter (DSC), thermogravimetric analysis (TGA) and tensile test in detail. The results showed that shell powder mostly homogeneously dispersed in the PHBV matrix, and the crystallization behavior of the PHBV/shell powder composites changed with different shell powder content. Moreover, the thermal stability of the composites decreased with the increasing content of shell powder. The tensile strength and elongation at break of the composites were improved compared to neat PHBV.
