Mechanically Robust, Reprocessable, and Light-Controlled Healable Solvent-Free Lignin-Containing Polyurethane Elastomers Based on Dynamic Phenol-Carbamate Network

Macromolecules, Год журнала: 2025, Номер unknown

Опубликована: Янв. 9, 2025

In this study, we introduce an innovative one-step, solvent-free approach for preparing lignin-containing polyurethane elastomers (LPUes) with nanomicro phase-separated structure and dynamic dual-cross-linking networks comprising both phenol-carbamate bonds (PCBs) hydrogen bonds. This distinctive structural design imparted exceptional mechanical properties to the LPUes. The sample containing 22.9 wt % phenolized lignin exhibited tensile strength of 44.6 MPa, elongation at break 714.6%, toughness 148.0 MJ/m3. abundance PCBs also conferred remarkable reprocessing capabilities, these LPUes retaining over 98% 94.4% after two hot-pressing cycles. Moreover, incorporation endowed photothermal properties, facilitating efficient light-controlled self-healing shape-memory functionalities. work offers pathway harmonize thermal adaptability in development sustainable high-performance LPUes, thereby opening their avenues diverse potential applications.

Functional components and antioxidant activity were improved in ginger fermented by Bifidobacterium adolescentis and Monascus purpureus

LWT, Год журнала: 2024, Номер 197, С. 115931 - 115931

Опубликована: Март 1, 2024

Microbial fermentation, a widely used food processing technology, enhanced the biological activity and nutritional profile of raw materials. The impact fermentation by Bifidobacterium adolescentis Monascus purpureus on functional components antioxidant ginger was investigated. results showed that fermented two strains notably increased content gingerol, total flavonoids, polyphenols, its capacity as measured various assays such DPPH, ABTS, FRAP. active were superior in M. compared to B. adolescentis. comparison organic acid demonstrated lactic succinic adolescentis, while acetic acid, fumaric citric purpureus. Pearson correlation analysis positive relation between pigments, Monacolin K, capacity. Therefore, has potential enhance ginger. This study might have implications for development ginger-based products theoretical basis deep

Kraft (Nano)Lignin as Reactive Additive in Epoxy Polymer Bio-Composites

Polymers, Год журнала: 2024, Номер 16(4), С. 553 - 553

Опубликована: Фев. 18, 2024

The demand for high-performance bio-based materials towards achieving more sustainable manufacturing and circular economy models is growing significantly. Kraft lignin (KL) an abundant highly functional aromatic/phenolic biopolymer, being the main side product of pulp paper industry, as well recent 2nd generation biorefineries. In this study, KL was incorporated into a glassy epoxy system based on diglycidyl ether bisphenol A (DGEBA) amine curing agent (Jeffamine D-230), utilized partial replacement DGEBA prepolymer or reactive additive. D-230 by pristine (unmodified) up to 14 wt.% achieved while KL–epoxy composites with 30 exhibited similar thermo-mechanical properties substantially enhanced antioxidant compared neat polymer. Additionally, effect particle size investigated. Ball-milled kraft (BMKL, 10 μm) nano-lignin (NLH, 220 nm) were, respectively, obtained after ball milling ultrasonication were studied additives in same system. Significantly improved dispersion obtained, mainly nano-lignin, which fully transparent lignin–epoxy higher tensile strength, storage modulus glass transition temperature, even at loadings. Lastly, glycidylized (GKL) prepolymer, 38 fossil-based DGEBA. GKL transparency. All lignins extensively characterized using NMR, TGA, GPC, DLS techniques correlate justify polymer characterization results.
