Stereocomplex Crystallization Induced Significant Improvement in Transparency and Stiffness-Toughness Performance of Core-Shell Rubber Nanoparticles Toughened Poly(l-lactide) Blends

Huili Liu et al.

Summary: This study presents a promising strategy to improve the transparency and stiffness-toughness performance of PLLA blends toughened with BAMMA core-shell rubber nanoparticles by utilizing SC crystallization. The construction of SC crystallites in the PLLA matrix prevents nanoparticle aggregation and promotes the formation of a network-like structure, leading to enhanced toughening efficiency and transparency.

Synergistic effect of plasticizer and nucleating agent on crystallization behavior of polylactide during fused filament fabrication

Xia Gao et al.

Summary: Addition of plasticizer PEG and nucleating agent TMC in PLA matrix can tailor the crystallization behavior of FFF-printed PLA parts. At a bed temperature of 60 degrees C, PEG showed a stronger effect on crystallization behavior compared to TMC, leading to an increase in crystallinity. Shear-induced crystal structures had negligible influence on the final crystallinity of PLA parts.

Highly Tough and Thermally Stable Polylactide Blends Compatibilized with Glycidyl Methacrylate-Grafted Polypropylene

Ji-Su Lee et al.

Summary: By utilizing an efficient masterbatch melt-compounding process, eco-friendly and sustainable PLA materials with improved toughness, thermal stability, and processability are developed through PLA-dominant blends with glycidyl methacrylate-grafted polypropylene loadings. The specific interactions between PLA and PPGMA, along with the compatibilizing effect of PPGMA-g-PLA, contribute to enhanced properties such as thermal decomposition temperatures and impact strength.

Synergistic effects of chain dynamics and enantiomeric interaction on the crystallization in PDLA/PLLA mixtures

Tongxin Lv et al.

Summary: Intra- and inter-molecular interactions are crucial in polymer chain dynamics, affecting polymer crystallization behavior and structure. Enantiomers like PLLA and PDLA are important nucleation sites for PLA crystallization. The addition of a stereocomplex can promote homopolymer crystallization in mixtures containing PDLA, with the degree of influence depending on factors like cooling rate.

Importance of Low-Temperature Melt-Mixing on the Construction of Stereocomplex Crystallites with Superior Nucleation Efficiency in Asymmetric Poly(L-lactide)/Poly(D-lactide) Blends

Ju Yao et al.

Summary: In asymmetric poly(L-lactide)/poly(D-lactide) blends, achieving high-efficient formation of finely dispersed stereocomplex crystallites can be challenging due to competition between stereocomplexation and chain mixing. Pre-mixing PLLA and PDLA chains can lead to decreased formation efficiency of SC particles, despite smaller particle size. Direct mixing at lower temperatures is more effective for constructing SCs with superior nucleation efficiency, compared to common melt-processing conditions.
