Fluidic lignin with ultra-low glass transition temperature (Tg < −57 °C): a versatile polyelectrolyte solvent platform

A series of deep eutectic supramolecular lignin polyelectrolytes with ultra-low T g values ranging from −57 to 9 °C were generated using a eutectic/supramolecular polymerization strategy, allowing access to flowable, adaptive, and bulk supramolecular materials.
