Interchain Spacing Expansion Effect Mediated by Green Solvent System: A Conductive Hydrogel With Multifunctional Energy Storage and Sensing Integration for Flexible Electronics
Flexible conductive hydrogels are often hindered by non‐green fabrication, performance trade‐offs, and additive‐dependent functionalization. Herein, we establish a triple strategy of “green preparation–structural synergy–multifunctional integration”. With wood vinegar, deep eutectic solvent, polyvinyl alcohol, chitosan...
