Exploring Lignin Conformation in Organic and Deep Eutectic Solvents Using Small-Angle Neutron Scattering.

ABSTRACT: Lignin, a structurally intricate and heterogeneous phenolic biopolymer, holds considerable promise as a sustainable alternative to petrochemical-derived materials across diverse applications in the energy and materials sectors. However, precise lignin molecular weight and structure determination remains challenging due to its intrinsic tendency to aggregate in solution and the absence of chemically analogous polymer standards for chromatographic techniques. By employing small-angle neutron scattering, this study aims at precise measurement of lignin's polymeric conformation, aggregation behavior, and radius of gyration in organic gel permeation chromatography/NMR solvent, tetrahydrofuran (THF), and in an emerging class of solvent systems known as deep eutectic solvents (DES).
