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.

Contributions to Tobacco and Nicotine Research, 2022 High lignin content of tobacco stem has been addressed as a drawback for its utilization on manufacture of reconstituted tobacco sheet. Therefore, the solvothermal method using ethylene glycol was investigated for the removal of lignin from tobacco stem.

Improved Lignin Polyurethane Properties with Lewis Acid Treatment [PDF]
, 2012 Chemical modification strategies to improve the mechanical properties of lignin-based polyurethanes are presented. We hypothesized that treatment of lignin with Lewis acids would increase the concentration of hydroxyl groups available to react with ...

An environmentally benign antimicrobial nanoparticle based on a silver-infused lignin core [PDF]
, 2015 Silver nanoparticles have antibacterial properties, but their use has been a cause for concern because they persist in the environment. Here, we show that lignin nanoparticles infused with silver ions and coated with a cationic polyelectrolyte layer form

Lignin Structural Changes During Liquefaction in Acidified Ethylene Glycol [PDF]
Journal of Wood Chemistry and Technology, 2012 Beech (Fagus Sylvatica) milled-wood lignin was used as a model substrate in a study of lignin-catalyzed liquefaction in the presence of p-toluene sulfonic acid monohydrate (PTSA) or sulphuric acid as the catalysts. The structural changes that lignin undergoes during the treatment were studied by NMR spectroscopy, FTIR, size-exclusion chromatography ...

A statistical theory of polymer network degradation [PDF]
, 2014 A statistical theory was proposed for the degradation (random scission of chains) of a network having f-functional nodes in the case where all chains contain equireactive groups and a chain scission event does not create new groups or suppress more than ...
