Abstract

Poly(3-hydroxybutyrate) (PHB) and poly(3-hydroxybutyrate-

-3-hydroxyvalerate) (PHBV) undergo an ageing process on storage at room temperature which renders them increasingly mechanical property deterioration

which has been attributed to the development of secondary crytallisation. The formation of

crystals by tensile induction can effectively inhibit the secondary crystallization and improve the mechanical properties. This paper reviews the

crystal structure of PHB and PHBV

and the formation and transformation mechanism of

crystal. The influence of

crystal structure on mechanical properties and the research progress of toughening mechanism are summarized emphatically. The relationship between

crystal structure and degradation properties was briefly reviewed. Finally

the gaps in the research of

crystal structure are analyzed.
