Physicochemical properties of PLA lignin blends
Open accessAbstract
Commercial alkali lignin (CL) and lignin extracted from almond shells by organosolv process (OL) were used for the preparation of blends with poly(lactic acid) (PLA) with different percentages (0.5, 1, 5, 10 and 20%) by extrusion method. Both lignins were acetylated to improve their compatibility with PLA. PLA/acetylated lignin blends exhibited greater compatibility than non-acetylated PLA/lignin. Characterization of lignins has been performed using HPLC, FT-IR, GPC, DSC and TGA. All lignins showed high purity. Acetylated lignins had lower Tg and higher thermal stability than original lignins. Thermal and mechanical properties of different blends were investigated. Morphology before and after hydrolytic degradations of blends with 5% of different lignins were also investigated. The addition of acetylated lignin appears to prevent hydrolytic degradation of PLA. Lignin content increased the thermal stability of PLA but does not favor the crystallization of PLA. Maximum strength decreased with high percentages of originals lignins. However, PLA/acetylated lignin blends remains fairly constant, even at high percentages. In all cases, the elongation at break was increased.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
