Supramolecular-Engineered Bamboo Lignin Polymer with Enhanced Mechanical and Electrical Properties for Flexible Electronics.

ABSTRACT: Ionogels have emerged as a groundbreaking category of materials for flexible electronics, yet the challenge of integrating high mechanical stretchability, rapid electrical response, and reliable self-repair in bio-based ionogels persists. Here, a lignin-derived ionogel is presented, designated P(LA-TA)-gel, through a straightforward, one-step solvent-free process. By leveraging arginine-grafted lignin-terminated polythioctic acid and incorporating imine and hydroxyl groups into the supramolecular framework, the P(LA-TA)-gel with both dynamic disulfide bonds and supramolecular hydrogen bonds achieves effective energy dissipation channels. This configuration adeptly balances mechanical stretchability-exhibiting a strain of 1233%-with dynamic reversibility, evidenced by an adhesion strength o
