Polymerizable Deep Eutectic Solvents‐Enabled High‐Lignin‐Density Networks for Ambient Multi‐Scale Fabrication of Multifunctional and Extreme Environment Adaptable Soft Devices

ABSTRACT Skin‐like soft electronics exploiting gels containing biomass‐derived components raise increasing research attention, in which multifunctional lignin has been extensively explored. Nevertheless, elevating the lignin loading usually sacrifices the performance, limiting their application potentials. Herein, we develop a unique polymerizable deep eutectic solvent (PDES) consisting of a quaternary ammonium monomer and lactic acid to incorporate with high‐density lignosulfonate (LS) of > 20 wt.% and address the performance trade‐offs. The lignin‐induced self‐catalytic polymerization associated with electrostatic assembly enables room temperature gelation within < 5 min and ambient‐air…
