Abstract Flexible temperature sensors often use gels to achieve skin‐inspired softness, but the water evaporation and freezing of hydrogel leakage ionogel, cause unstable signal transmission inaccurate measurement at sub‐zero temperatures. Here steady hypothermic sensing is achieved by designing a supramolecular elastomer containing two types segments: liquid‐free iontronic segment transmit electrical charges prevent ion leakage, neutral with pendant chains damp vibration for stable transmission. The exhibits excellent tensile properties, adhesiveness, self‐healing, ionic conductivity A wireless system fabricated based on supermolecule elastomer, realizing accurate, steady, sensitive real‐time detection. Especially, sensor coefficient resistance (TCR) 8.87% °C −1 from −20 −15 °C, three five times higher than that most flexible sensors. There no significant difference in detected this an infrared thermal imaging camera. Such represents step toward highly accurate cold chain transportation beyond.

Abstract Underwater adhesion plays a vital role in various fields, e.g., underwater labeling or coating, actuators and surgery. However, it is big challenge to design adhesives with high durability, especially for burgeoning supramolecular due their dynamic nature. Herein, ionic liquids (ILs) are explored as directly via fluorinated branched modification strategy. The subsequent self‐assembly of these ILs promotes the formation robust hydrophobic polymeric networks, thus effectively driving both cohesion outstanding interfacial adhesion. Owing this strategy, IL‐based aggregates can obtain high‐performance strength (up 4.11 MPa) well great cyclability. further showcase that they benefit assembly hydrogel units achieving diverse shapes. More importantly, molecular mechanism elucidated underlying analogs. These fundamental understandings open door functional while facilitating adhesive materials.
