Summary: A one-step dynamic vulcanization strategy was adopted to prepare PLA/PU/MXene nanocomposites with balanced stiffness and toughness. The results showed that MXene content had a significant impact on the properties of the materials, and the pre-intercalation treatment achieved good dispersion of MXene in the polymer matrix.

Summary: In this study, cellulose nanofibrils were modified by catalyzed lactic acid esterification in an aqueous medium. The modification improved the mechanical properties of the films, reduced water absorption, and enhanced barrier properties. The addition of lactic acid-grafted CNF to PLA composites improved water vapor permeability, showing potential for environmentally friendly modification of CNFs.

Summary: The study showed that the presence of MXene in nonisothermal melt crystallization increases crystallinity and shortens half-crystallization time, but does not change the crystallization peak temperature of PLA. In nonisothermal crystallization from the glassy state, the incorporation of MXene decreases the cold crystallization peak temperature and reduces crystallinity marginally, without affecting the half-crystallization time of PLA.

Summary: This study investigates the effects of cellulose nanocrystals (CNC) from bamboo fiber on the properties of poly (lactic acid) (PLA)/poly (butylene succinate) (PBS) composites. The addition of CNC improves the thermal stability, tensile strength, and modulus of the composite, while reducing elongation at break.

Summary: This study focused on developing composite materials based on PLA reinforced with bentonite nanoparticles to produce films with improved barrier properties against water vapor transportation. The dispersion of nanoparticles reduced water vapor diffusion by over 22% and met migration standards for food packaging. However, the presence of nanoclays decreased the biodegradable capacity of the materials.

Summary: This study investigates the enhancement of crystallinity and gas barrier properties of polylactic acid (PLA) by adding poly(hydroxybutyrate) (PHB) and glycerol triacetate (GTA) functionalized chitin nano crystals (ChNCs). The results show that the addition of ChNCs improves the crystallinity and mechanical properties of PHB, as well as significantly reduces the permeability of oxygen and carbon dioxide. This study demonstrates that adding ChNCs can achieve suitable gas barrier properties for food packaging films.

Summary: In this study, PLLA films were surface-modified using different solutions, leading to changes in their structure and properties. The modification with PDLA weakened the crystal structure of the films, while modification with PDLAG increased the stereocomplex (SC) structure and decreased the homogeneous crystal (HC) structure.

Summary: Poly(lactic acid) (PLA) is a promising biobased substitute for fossil-derived polymers due to its compostability, biocompatibility, renewability, and good thermomechanical properties. However, PLA has some shortcomings, and different end-use sectors require specific properties. The addition of different nanofillers has been investigated to enhance the properties of PLA, and this review paper provides an overview of the synthetic routes, properties, and applications of PLA nanocomposites.

Summary: Cellulose nanocrystals (CNCs) were incorporated into poly-L(lactid acid) (PLLA) matrices using a single melt-processing mode with poly(ethylene glycol) (PEG) as carrier. The effects of CNC content on nucleation and reinforcement efficiency, as well as mechanical properties and melt rheology, were investigated. The results showed that adding CNCs and aminated CNCs (Am-CNCs) significantly improved the tensile modulus and strength, with the best performance at 2% nanofiller content, especially for Am-CNCs. Similar trends were observed in the melt rheology of the PLLA/PEG blend.

Summary: In this study, biodegradable blends of PGA and PBAT with in situ compatibilization using MDI were prepared. The addition of PBAT was found to increase the complex viscosity and storage modulus of the blends, leading to improved compatibility and impact strength. The morphology of the dispersed phase evolved from spherical structure to in situ microfiber, enhancing interfacial adhesion and improving toughness.

Summary: In this study, nanocomposites of poly(lactic acid) (PLA) were prepared by incorporating metal organic framework (MOF-5) and metal organic framework/graphene oxide (MOF-5/GO) fillers through a melt extrusion process. The compatibility of the fillers with PLA was confirmed by morphological and FT-IR analysis. The rheological behavior of the PLA nanocomposites indicated good dispersion of the fillers. The incorporation of MOF-5/GO significantly reduced water vapor permeability (WVP), making it a promising material for packaging applications.

Summary: The role of a polymer as a retarder additive is to improve the workability and properties of gypsum paste. This study investigated the influence of water-soluble cellulose derivative HPMC on the setting kinetics, properties, and microstructure of gypsum. The results showed that the presence of HPMC modified the hydration/crystallization process of gypsum, reducing the K value but suggesting a three-dimensional diffusion-controlled mechanism based on the value of n. The mechanical properties of the gypsum plaster composites were correlated with the sample's microstructure.
