Flame-Retardant Ionogel Enabled by Lignin Molecular Networks for Fire Rescue.

ABSTRACT: Ionogel intended for fire environments encounters considerable challenges stemming from intrinsic limitations, such as inadequate heat resistance and potential damage to their structural networks. Here, a glycol lignin ionogel (GLI) with integrated flame-retardant, waterproof, and sensing capabilities for smart firefighting auxiliary equipment is presented. The ionogel, synthesized from the molecular network construction of Gly-lignin, 1-butyl-3-vinylimidazole tetrafluoroborate (BVIMBF₄), and benzyl methacrylate (BZMA), forms a stable and elastic 3D conductive network through both chemical and physical crosslinking. This structure imparts remarkable mechanical properties, including considerable adhesion (30.4 kPa on flame-retardant gloves), tensile strength (5.8 MPa), and high i
