Flame‐Retardant Ionogel Enabled by Lignin Molecular Networks for Fire Rescue
Advanced Science, EarlyView.Wearable sensors for harsh, high‐temperature, fire‐prone environments face challenges in heat resistance and stability. This study introduces a flame‐retardant, waterproof glycol lignin ionogel (GLI) with a robust 3D network, exceptional tensile strength, strong adhesion, biocompatibility, eco‐safety, and dual temperature‐motion sensing, even after ...
