Ion induced ultra-tough single-network ionogel

Abstract

Ionogels with high fracture strength (16.90 MPa), high Young's modulus (119.97 MPa), high tensile toughness (96.86 MJ m⁻³), high fracture energy (119.07 kJ m⁻²) and excellent stretchability (∼1300%) were prepared by varying the ions of solvents. This strategy can be applied to other monomers and ionic liquids, offering a promising way to prepare an ultra-tough ionogel.
