With the imperious demand of wearable electronics, the development of E-skin has attracted a lot of attention. As a kind of E-skin, i-skin consisting of ionic liquids and elastic matrix stands out through its ionic transmission mechanism similar to human real biological system. Additionally, the ability of i-skin to restore its functionality after accidental damage is crucial for long-term use. And due to the diverse scenarios, achieving self-healing characteristics both in normal and underwater environments is strongly required. Here, we present a rational design of polyurethane with dynamic borate bonds and hydrophobic soft segments as the self-healing driving force. Then, a novel i-skin was fabricated by this polyurethane and [BMIM+][TFSI-]. Fast self-healing ability was demonstrated at ambient temperature and faster speed underwater as well, which significantly improves the durability. Moreover, this i-skin exhibits remarkable sensitivity attributed to excellent ion conductivity. |
