Novel and Efficient Diethylene Glycol/H2O Solvent for Lignin Dissolution
BioResources, 2016 Novel lignin solvents were developed by adding H2O to diethylene glycol (DEG). The solubility of lignin in the DEG/H2O solvents was determined at 25 °C, and the effect of mass ratio of H2O to DEG on lignin solubility was investigated.

Lignin‐Based Solid Polymer Electrolytes: Lignin‐Graft‐Poly(ethylene glycol) [PDF]
Macromolecular Rapid Communications, 2020 AbstractLignin is an aromatic‐rich biomass polymer that is cheap, abundant, and sustainable. However, its application in the solid electrolyte field is rare due to challenges in well‐defined polymer synthesis. Herein, the synthesis of lignin‐graft‐poly(ethylene glycol) (PEG) and its conductivity test for a solid electrolyte application are demonstrated.
