Summary: In this study, Cellulose-grafte-poly(L-lactide) (C-g-PLLA) copolymers were synthesized as effective compatibilizers for cellulose-PLLA composites. The effect of the molar substitution (MSPLLA) of the grafted PLLA side chain and the feeding amount of this copolymer on the properties of the composites was investigated. The results show that the copolymer improved the interfacial compatibility and the mechanical properties of the composites.

Summary: Core-shell fibres (CSFs) offer a simple route to multifunctional hybrid materials for a wide range of applications. The CSFs in this study were designed with a hydrophilic core and hydrophobic shell, serving as potential carriers for water-soluble bioactive agents and providing protective antibacterial properties. The fibres were shown to be non-toxic to normal human dermal fibroblast cell lines and have the potential for smart delivery fabrics/dressings.

Summary: This study proposes a new approach to tolerate stereoerrors in the polymer by crowding them in a stereogradient copolymer. A zirconium complex of an amine tris(phenolate) ligand is used as a catalyst for the ring opening polymerization of meso-lactide at room temperature, and stereogradient copolymers are formed in the polymerization of mixtures of meso-lactide/L-lactide at 180 degrees C. These stereogradient copolymers exhibit enhanced crystallinities compared to stereorandom copolymers obtained with tin octanoate.

Summary: Researchers have successfully designed two-dimensional assemblies with structural complexity by utilizing the distinct interfacial morphology of soft particles. They found that core-shell particles can form complex chain and cluster structures under interfacial compression. Through a combination of experimental, simulation, and theoretical analysis, the interaction parameter of the system was narrowed down to between 0.9 and 2.

Summary: Using polysaccharide nanocrystals, such as chitin nanocrystals, as nanofillers for biodegradable aliphatic polymers is an attractive method for developing fully degradable nanocomposites. The incorporation of chitin nanocrystals in poly(L-lactide)/poly(D-lactide) blends promotes the formation of stereocomplex crystallites and accelerates overall crystallization kinetics. The nanocomposites exhibit higher stereocomplex crystallization temperatures and lower activation energy compared to the blend. However, the presence of chitin nanocrystals reduces the fraction of stereocomplex crystallites due to the nucleation effect, despite an increased rate of homocrystallization. This study provides valuable information for the use of chitin nanocrystals as nucleators for polylactide stereocomplexes.
