It is now well recognized that the production of petroleum-based packaging materials has
created serious ecological problems for the environment due to their resistance to …

Detailed knowledge of the organization of amorphous and crystalline phases in a
semicrystalline polymer such as poly (l-lactic acid)(PLLA) is crucial for complete …

Poly (lactic acid) or PLA is currently considered as one of the most promising substitutes of
conventional plastics, with low environmental impact, especially for food packaging …

Poly (lactic acid)(PLA) is the most traded biodegradable and biobased material. It is largely
used as eco-friendly substitute of conventional plastics. Nevertheless, one of the main …

The effects of the crystallinity and polymorphism of PLLA and PDLA–PLLA 50: 50 blends on
the free volume and transport properties have been studied. In the case of PDLA–PLLA 50 …

Semicrystalline polylactide (PLA) films with controlled morphology were produced by
thermal crystallization to optimize the oxygen barrier properties. The crystalline morphology …

The physical ageing of poly (l-lactic acid)(PLLA) samples crystallized in a wide temperature
range, is compared, through the analysis of the enthalpy relaxation, with the behavior of a …

Hydrolytic degradation of poly (lactic acid)(PLA-C) and PLA-nanocomposite produced with
organomodified montmorillonite at 5 wt%(PLA-OMMT) were investigated in pure water, 50 …

Fragility index and cooperativity length characterizing the molecular mobility in the
amorphous phase are for the first time calculated in drawn polylactide (PLA). The …

In most cases, a three-phase model consisting of crystalline domains surrounded by rigid
amorphous areas dispersed in the mobile amorphous phase is required and eventually …
