- New PLA-based materials need to be developed to allow a good balance between environment-friendliness and product properties for engineering/durable applications.
- The blending of bio-based, brittle, and mostly amorphous PLA with semi-crystalline PAs (bio-sourced (e.g., PA11), or not (PA12)) has been reported to lead to high-performance materials (toughness, ductility, increased HDT and better thermal resistance, others).
- The low crystallinity of PLA is believed to strongly influence its final properties and to limit the applications of PLA-based products.
- Why not, the use of PLA (NA/nucleating agent) with high crystallization ability, to tune up the properties of PLA/PA blends !?
- Our paper aims to show the experimental pathways followed to produce novel PLA/PA blends using PLA(NA) characterized by improved crystallization kinetics (impressive degree of crystallinity). Moreover, it highlights with the possibility to tailor the morphology and properties of PLA/PA blends with special compatibilizers, such as epoxy styrene-acrylate oligomers.

The authors would like to share this contribution and have your opinion about the approach developed in this paper! Thank you.

Hello Marius, I though you was retired :)
I agree that PLA / PA are scientifically very interesting. We publish a few paper on these blends. For instance, we find that nanofibrillar microstructures are easily formed / controled) and that the compatibility could be tuned. I will also try to publish a paper on peculiar crystallization effects at PLA / PA interfaces. By the future, probably investigate their piezoelectric properties. Anyway, this subject is still alive. However, I guess that industrial application are more complicated by now...
Best regards,

Dear Dr. Cedric Samuel, Dear Colleague(s),
Not to delay more, thank you for sharing your opinion!
I would like to mention that your research group has already important contributions in the field of PLA/PA blends (scientific papers, theses, and so on), therefore I would like to recommend their use for more information on this subject.
Based on my long R&D experience with PA and PLA, I will add only a few comments:
