Balancing mechanical-thermal-electrical properties in cellulose ionogels via crystallization-induced molecular assembly.

ABSTRACT: Cellulose-based ionogels are promising for flexible electronics and energy devices, yet their performance is often constrained by the trade-offs among mechanical robustness, ionic conductivity, and thermal stability. Here, we propose a synergistic strategy that integrates dual-ions complexation with crystallization-induced molecular assembly to fabricate a cellulose ionogel. This strategy results in a comprehensive ionogel (noted as Cry-gel) with high mechanical strength (2.3 MPa in tension and 5.3 MPa in compression) and high ionic conductivity (96.8 mS cm^-1). Moreover, the Cry-gel can maintain impressive structural stability across a temperature range of -40 to 80 °C. Flexible thermoelectric devices and smart sensors derived from Cry-gels demonstrate a voltage of 0.28 V at a t
