The mechanical properties of the neat PLA,
the PLA and Joncryl-based nanocomposites were also considered.
The semi-crystalline PLA exhibited a high tensile modulus and
strength while it had a very low elongation at break and toughness.
However, a good dispersion and distribution of clay platelets and
an increased molecular weight in Joncryl-based nanocomposites
led to significant increases in the modulus, drawability and toughness
compared to the neat PLA.
