摘要

Ionogels are promising materials for flexible electronics due to their continuousconductive phase, high thermal and chemical stability. However, alarge amount of ionic liquid is required to get high conductivity, resulting in asharp decline in the mechanical properties. Therefore, it is a great challengeto prepare ionogels with both high conductivity and mechanical properties,which is important for their practical applications. Herein, ionogels withhigh mechanical strength and stretchability, extraordinary ionic conductivity,excellent transparency, outstanding durability, and stability are fabricated withcrosslinked polymer, ionic liquid, and lithium salt. The adoption of lithiumsalt can significantly improve both the mechanical strength and stretchability,which is a common dilemma in material science, and simultaneously, addressthe conflict between mechanical strength and ionic conductivity in ionogels.It is primarily corresponding to the microphase-separation effects inducedby the lithium bonds formed between lithium ions and carbonyl groups onthe polymer networks. Ionotronics including resistance-type sensors forstrain and temperature sensing and triboelectric nanogenerators with stableoutput performance are fabricated. Moreover, ionogel-based microcircuitand sensing arrays with high resolution and accuracy are fabricated throughdigital light processing printing technology. The ionogels have great promisefor various ionotronics in many fields.
