Problems solved by technology

It is difficult for hydrogel self-healing ionic conductors to avoid water evaporation during use, resulting in salting out, which in turn leads to a decrease in the conductivity of the fabricated ionic device
There is a risk of ionic liquid leakage in the ion gel self-healing conductor, which affects the experience and effect of its ionic devices
[0003] Moreover, it is difficult for the aforementioned self-healing ionic conductors to simultaneously achieve transparency and stretchability, hindering their application in optically-related flexible electronics.
Therefore, the preparation of long-term stable self-healing ionic conductors suitable for ionic devices remains a challenge.

technical field [0001] The present application relates to the field of ion conductors, in particular to an all-solid self-repairing ion conductor, a preparation method thereof, and an ion device. Background technique [0002] Traditional self-healing ionic conductors are mainly designed using hydrogels and ionogels. It is difficult for the hydrogel self-healing ionic conductor to avoid the evaporation of water during use, resulting in salting out, which in turn leads to a decrease in the conductivity of the fabricated ionic device. There is a risk of ionic liquid leakage in the ionic gel self-healing conductor, which affects the experience and effect of its ionic devices. [0003] Furthermore, it is difficult for the aforementioned self-healing ionic conductors to simultaneously achieve transparency and stretchability, hindering their application in optically-related flexible electronics. Therefore, the preparation of long-term stable self-healing ionic conductors suitable...
