Abstract: 

Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) has lower melting point (thus wider processing window), as well as better toughness compared with poly(3-hydroxybutyrate). Due to the introduction of non-crystallizable comonomer 3-hydroxyhexanoate, however, the crystallization rate becomes extremely slow and broad melting range also emerges. Here we studied crystallization kinetics in terms of DSC and POM-Raman combination techniques , as well as SAXS, to investigate PHBH crystal formation and evolution in some details, nucleation/spontaneous fluctuation at the early stage will be mentioned, and melting of different lamellar populations will also be discussed.

This will be a presentation with ample room for discussion.
