High-Barrier, Photothermal Conversion, and Antibacterial Composite Enabled by Kraft Lignin-Coated Cellulose Paper for Plastic Replacement

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 12, 2024

Paper-based materials demonstrate considerable potential as a substitute for plastic packaging. However, their limited barrier properties, singular functionality, and intricate preparation methods pose challenges to further advancement. Specifically, the inadequate adversely impacts preservation of paper-based packaging under conditions characterized by high humidity prolonged exposure sunlight. Herein, refined strategy is proposed direct enhanced production biodegradable multifunctional paper. Lignin deposited onto surface cellulose paper (CP) via vacuum filtration followed conversion into lignin/cellulose (LCP) through simple hot-pressing process. The resulting LCP exhibits outstanding properties (Kit grade 12, water vapor permeability 197 g/(m2·24 h) at 37 °C 90% RH) wet strength (50.79 MPa). Moreover, prepared also rapid stable photothermal capability, along with remarkable antibacterial activity (photothermal rate >99.9%). overall numerous advantages, encompassing an intact biobased composition, degradability, environmental protection, exceptional properties. Therefore, it presents optimal alternative conventional materials, offering efficient solution product storage across diverse environments while providing sustainable cost-effective approach materials.

pH-responsive magnetic CuFe2O4-PMAA nanogel conjugated with amino-modified lignin for controlled breast cancer drug delivery

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Oct. 29, 2024

In this study, a novel magnetic and pH-responsive nanocarrier was developed, incorporating both natural synthetic polymers, for delivering curcumin (CUR) to breast cancer cells. For purpose, CuFe2O4@poly(methacrylic acid) (CuFe2O4@PMAA) nanogel developed conjugated with amino-modified lignin (Lignin-adipic acid dihydrazide conjugate, Lig-ADH) achieve the CuFe2O4@PMAA@Lig-ADH nanocarrier. The morphology, structure, physical properties of synthesized nanomaterials were examined using range techniques, including transmission electron microscopy (TEM), field emission scanning (FESEM), Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), energy dispersive (EDX), vibrating sample magnetometer (VSM). exhibited spherical shape, an average diameter approximately 15 nm, demonstrated good responsiveness. Moreover, in vitro drug release found be pH-dependent, increased rate acidic conditions. To evaluate cytotoxicity, survival MCF-7 cells measured MTT assay 24 h. Notably, CuFe2O4@PMAA@Lig-ADH@CUR CUR significant cytotoxic effects, effectively eliminating IC50 values 39.80 µg/mL 4.27 µg/mL, respectively. Also, intracellular uptake NPs confirmed by FITC DAPI staining after 4 This research highlighted potential as highly effective nano-delivery system straightforward method utilizing renewable lignin.

Two approaches to prepare cationic lignin‐based adsorbents for efficient removal of phosphate ion from wastewater

Journal of Applied Polymer Science, Journal Year: 2024, Volume and Issue: 141(32)

Published: May 24, 2024

Abstract In this work, two types of cationic lignin‐based adsorbents (AL‐METAC and AL‐GTA) were prepared through free radical polymerization or etherification reaction alkali lignin with 2,3‐epoxypropyl‐3‐trimethylammonium chloride methylacrylloxyethyl trimethyl ammonium (METAC). The contents quaternary groups in the adjusted by changing dosages METAC to fabricate excellent adsorption capacity. structures, aqueous solubility, physical properties analyzed. Meanwhile, effects dosage, pH value solution, temperature, ionic strength on capacity also These exhibited outstanding affinity for phosphate, a maximum removal efficiency 51.8 73.2 mg/g, respectively. processes followed pseudo‐second‐order Langmuir models well. addition, AL‐GTA higher than AL‐METAC. Moreover, AL‐METAC still retained 69.7% 69.0% after four times regeneration. fabricated have potential applications phosphate from wastewater, which would promote high‐value application lignin.
