Molecular understanding of the morphology and properties of lignin nanoparticles: unravelling the potential for tailored applications

Abstract

Studies have shown that the size of LNP depends on the molecular weight (Mw) of lignin. There is however need for deeper understanding on the role of molecular structure on...

Towards a deep understanding of the biomass fractionation in respect of lignin nanoparticles formation

“…3a and b). Previous studies reported that smaller LNPs were successfully prepared with higher molar mass lignin [30,42]. However, those statement is not consistent with the results of this study.…”

Green fabrication of fabric by ethanol/water solvent-mediated self-assembly of homogeneous lignin for oil–water separation

“…Previous studies have indicated that the self-assembly of lignin compounds is driven by hydrogen bonding, π–π interactions among aromatic groups within and between molecules, and hydrophobic interactions. 58,59 As the water content in the system increased, the polar segment of formic acid lignin compounds exhibited an affinity for water, leading to an escalation in the polar group content (carboxyl, hydroxyl). Conversely, the water molecules around the non-polar hydrophobic skeleton were excluded and repelled, therefore stabilizing the contact of non-polar regions.…”

Overcoming Challenges of Lignin Nanoparticles: Expanding Opportunities for Scalable and Multifunctional Nanomaterials

“…Additionally, there are some cases where hemicelluloses can stabilize lignin particles. , This stabilization of LNPs by attached polysaccharide chains is due to increased osmotic pressure when the particles approach each other, as the concentration of polysaccharide segments locally increases, causing a repulsive force. Recently, DFT calculations also support that the molecular structure of lignin strongly influences the formation of LNPs, so that flexible interunit linkages, specifically the β-O-4′ substructures, yield molecular folding resulting in intramolecular π–π stacking which presumably supports the assembly process …”
