Physical aging plays an important role in determining the long terms performance of polymers, especially PLA, whose Tg is close to ambient temperature.
Considering long term performances, PLA/PHBV/PODC blends are the most promising materials for the toughening of PLA. Indeed, for these blends significant improvement in the strain at break was observed, along with a limited depression of the Young modulus and the stress at yield in comparison to neat PLA, as well as animproved thermal stability.
