Randomized trial explores high-performance ionogels providing self-healing and durability, suggesting viable future applications in electronics.
Key Points
The research aims to develop ionogels that combine mechanical strength, self-healing properties, recyclability, and long-term durability under cyclic loading.
Synthesis of polyurethane elastomers with adipic dihydrazide and imidazolidinyl urea as chain extenders.
Complexation with ionic liquids to form PU–IL ionogels.
Evaluation of mechanical properties including tensile strength and cyclic load stability.
Ionogels demonstrated a tensile strength of 12.6 MPa and toughness of 85.7 MJ m −3.
Exhibited long-term cyclic load stability and strain sensitivity ranging from 0.1% to 200%.
Self-healing and recyclability were facilitated by a reversible hydrogen-bonding network.
