A Transparent, Self-Healing, Highly Stretchable Ionic Conductor

Self-healing materials can repair damage caused by mechanical wear, thereby extending lifetime of devices. Here, a transparent, self-healing, highly stretchable ionic conductor is presented that autonomously heals after experiencing severe mechanical damage.

A Transparent, Self-Healing, Highly Stretchable Ionic Conductor

We introduce a transparent, highly stretchable ionic conductor with autonomous self-healing capability by harnessing ion–dipole interactions as the dynamic bonds for self-healing. This material tolerates extreme strains exceeding 5000%, features an ionic conductivity of 104 S cm1, and shows high transparency across the visible spectrum with an average transmittance of 92%. More importantly, the material can completely heal mechanical properties within 24 h at room temperature without any external stimulus. We illustrate the unique combination of attractive properties of the transparent, self-healing, highly stretchable ionic conductor when used to electrically activate transparent artificial muscles that autonomously heal after severe mechanical damage.
