Scientists from Tokyo and Yokohama jointly developed an ion gel with high strength indicators, which can independently restore its structure under room temperature without any external influence. This new class material has tremendous potential to create flexible electronic devices.
Ion gels are now attracting more and more attention to researchers due to their unique properties, such as a low evaporation rate under normal conditions, high heat resistance and good ionic conductivity. However, scientists decided to add to this list the possibility of self-healing. They created an ion gel consisting of liquid salts and a double copolymer based on hydrogen bonds.
The introduction of hydrogen made it possible to significantly increase the strength of the material and achieve a complete regeneration of the damaged structure for 3 hours, without any environmental changes, such as light or temperature. The rehability of hydrogen bonds opens up a wide range of possibilities for improving electrochemical properties.

In the future, such gels will be able to find widespread use in flexible electrical engineering, making it durable and preventing from deformation. In addition, the double copolymer is able to absorb moisture from the air. Therefore, researchers plan to explore the prospects for its use in an open atmosphere for a long time and possible combinations with other ionic fluids.
