Fig. 1: Design of FRCI with high toughness and good deformability.
From: Tough fiber-reinforced composite ionogels with crack resistance surpassing metals

a Schematic of the FRCI composed of the CF fabric and supramolecular ionogel. The supramolecular ionogel is composed of polymer chains and ionic liquid through the cation-oxygen interactions and hydrogen bonding. b Photographs of the FRCI showing the bending and distorting processes. c Photographs of the FRCI showing crack resistance.
