Despite the profound features of polylactide (PLA) such as being originated from biomass and its biodegradability, PLA
has several drawbacks that limit its use in different applications. A series of these drawbacks could be according to its
glass transition temperature (Tg = around 60oC) and its very slow crystallization kinetics. In applications where the service
temperature require to be below 60oC, PLA behaves as a very brittle polymer, whereas in those cases where the service
temperature should be much wider beyond 60oC, PLA can easily be deflected by heat because the degree of crystallinity is not
high enough to provide the required rigidity. Moreover, a series of drawbacks originate from the PLA’s melt conditions. Due to
the low melt strength of PLA followed by its slow crystallization rate, forming the final products with required shape is not easy.
Similar scenario exists in processing of PLA/gas mixture to form high-quality foamed structures. In this work, it is shown that
the enhancement of PLA’s crystallization kinetics could significantly enhance its processability, formability and foamability,
and could widen its service temperature beyond its Tg, and further can improve the mechanical properties of its final products.
Furthermore, blending PLA with other biopolymers with high melt strength, high toughness and ductility could improve the
melt strength and processability of PLA, compensate its brittleness and enhance its mechanical properties. These approaches
provide new routes to extend the PLA’s usage in much wider commodity applications.
