Effect of electrospun stereocomplex PLA fibers and modified cellulose nanocrystals on crystallization of poly(L-lactic acid)

Zhengwei Wan et al.

Summary: In this study, different nanocomposites were prepared by blending electrospun stereocomplex PLA fibers (Sc-fibers) and PLLA grafted cellulose nanocrystals (g-CNCs) with PLLA matrix. Both types of nano-fillers were found to accelerate the crystallization rate of PLLA, with g-CNCs exhibiting stronger nucleation ability. However, the presence of both nano-fillers resulted in a decrease in PLLA crystallization due to the preferential formation of stereocomplex crystals on the surfaces of CNCs. Moreover, the mechanical properties of PLLA were enhanced, with the elongation at break increasing fourfold after incorporating both g-CNCs and Sc-fibers. This work provides insights for designing different nano-fillers, particularly for polymer matrices with low crystallization ability and brittleness.

Cooling rate guiding contradictory effect of thermal treated temperature on the crystallization of PLA racemic blends upon cooling

Yangyu Huang et al.

Summary: This work reported the contradictory effect of thermal treated temperature on the crystallization of PLA racemic blends upon cooling, guided by the cooling rate. It was found that higher cooling rates favored the formation of stereocomplex crystals (SCs). The separation between the enantiomeric chains in the racemic melt was proposed as the reason for the contradictory effect of the thermal treated temperature on the crystallization enthalpy of PLA racemic blends upon cooling. Lastly, Flash DSC was used to compare the crystallization kinetics of PLA racemic blends after thermal treatment at different temperatures, and the results verified the influence of the separation between the enantiomeric chains on the contradictory effect of the thermal treated temperature.

Summary: The study successfully improved the morphology and matrix crystallization of PLLA/D-PU blends by incorporating degradable polyurethane elastomers, leading to enhanced mechanical properties and a toughening mechanism revealed through observation of impact fracture surface.

Promoted formation of stereocomplex in enantiomeric poly(lactic acid)s induced by cellulose nanofibers

Qian Ren et al.

Summary: The addition of cellulose nanofibers (CNFs) significantly reduced the half-crystallization time of the PLLA/PDLA blend, and when 3% modified CNFs were incorporated, almost exclusively SC crystallites were formed with no HC crystallite presence. This was speculated to be due to enhanced interchain molecular interactions between CNFs and PLA, presenting a feasible and efficient method for producing high-performance PLA materials with exclusively SC crystallites.

Influence of Interfacial Enantiomeric Grafting on Melt Rheology and Crystallization of Polylactide/Cellulose Nanocrystals Composites

Hua-Gao Fang et al.

Summary: Incorporating surface-grafted cellulose nanocrystals (CNCs) with enantiomeric polylactide (PLLA or PDLA) can effectively modify PLLA, with stereocomplexation significantly improving interfacial strength. However, the study found that PLLA/CNC-g-L exhibited a higher crystallization rate compared to PLLA/CNC-g-D, due to its higher nucleation efficiency and faster growth rate. This difference in crystallization behavior was attributed to the presence of a small amount of sc-PLA at the interface in PLLA/CNC-g-L, which restricted PLLA diffusion but contributed less to generating crystalline nuclei.

Synthesis, stereocomplex crystallization, homo-crystallization, and thermal properties and degradation of enantiomeric aromatic poly(lactic acid)s, poly(mandelic acid)s

Hideto Tsuji et al.

Summary: This study investigated enantiomeric aromatic poly(lactic acid)s and their crystallization, thermal properties, and degradation. It was found that high molecular weight poly(L-mandelic acid) and poly(d-mandelic acid) exhibited predominant stereocomplex crystallization, while low molecular weight blends showed both stereocomplex and homo-crystallization. The aromatic poly(mandelic acid) had higher glass transition temperatures and lower melting temperatures compared to previously reported poly(lactic acid)s. The thermal degradation temperatures of the blends were higher than those of enantiomeric poly(lactic acid)s and similar to enantiomeric poly(2-hydroxybutanoic acid)s. The study also compared the crystallizability of aromatic poly(mandelic acid) and poly(phenyllactic acid).

Substantially Enhanced Stereocomplex Crystallization of Poly(L-lactide)/Poly(D-lactide) Blends by the Formation of Multi-Arm Stereo-Block Copolymers

Xingyuan Diao et al.

Summary: In this study, trace amounts of epoxy-functionalized small-molecule modifiers were introduced into enantiomeric blends during reactive melt-blending to enhance the formation of stereocomplex-type polylactide (SC-PLA). The results showed that the in situ generation of multi-arm stereo-block PLA copolymers significantly improved SC formation, even with only 0.5 wt% modifiers. The unique copolymers acted as compatibilizers, suppressing the separation of the alternately arranged PLLA/PDLA chain segments in the molten state. Furthermore, the generation of these copolymers did not significantly increase the melt viscosity of the blends, suggesting new opportunities for high-throughput processing of SC-PLA materials.

Polylactide aerogel with excellent comprehensive performances imparted by stereocomplex crystallization for efficient oil-water separation

Pengfei Chen et al.

Summary: Polylactide (PLA) aerogel is considered an ideal material for oil-water separation and absorption due to its renewability, biodegradability, and mechanical properties. However, its practical application has been hindered by poor heat resistance, durability, and separation performance. This study proposes a strategy of incorporating stereocomplex (SC) crystallites into PLA aerogels to overcome these obstacles. The resulting SC-PLA aerogels exhibit improved heat resistance, degradation resistance, hydrophobicity, and excellent oil-water separation capability. The absorption capacity of SC-PLA50 aerogel can reach 42 times its own weight, making it a potential solution for oil spill accidents and industrial wastewater treatment.

Summary: The study investigated the impact of block lengths, microdomain morphology, and stereocomplexation on the mechanical properties of PLA-b-PCL-b-PLA triblock copolymers. The synthesized materials, with tailored molecular weight, displayed a wide range of mechanical properties and were found to be potential biomaterials after biocompatibility testing using rat bone osteosarcoma cells.

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.
