Abstract Tissue adhesives are promising materials for expeditious hemorrhage control, while it remains a grand challenge to engineer superior formulation with instantaneous adhesion, on‐demand debonding, and the integration of multiple desirable properties such as antibacterial hemostatic capabilities. Herein, multifunctional supramolecular tissue adhesive based on guanidinium‐modified polydimethylsiloxane (PDMS) is introduced, driven by reversible microphase separation mechanism. By optimizing content guanidinium ions, precise control over cohesive strength, wettability achieved, resulting in strong adhesion under both dry wet conditions. Notably, nature allows convenient removal using medical‐grade alcohol, offering critical advantage easy debonding. Additionally, exhibits remarkable antimicrobial maintaining excellent biocompatibility hemocompatibility. Its underwater injectability supports minimally invasive surgical procedures. Furthermore, adhesive's ability incorporate solid particles enhances its versatility, particularly development drug‐embedded bioadhesives. This work addresses key challenges design via separation‐driven working principle, thereby opening new avenues advanced bioadhesives tailored enhanced wound care outcomes.

Abstract The current application of self‐healing solid omniphobic slippery coatings is severely constrained by the elevated temperature requirements for their mechanisms. This work presents first room‐temperature coating with exceptional transparency and robust liquid repellency across a wide range surface tensions. breakthrough accomplished incorporating minute quantity 1‐hexyl‐3‐methylimidazolium chloride ([Hmim]Cl) into rationally engineered amorphous polyurethane comprising perfluoroalkyl side chains. In‐depth studies reveal that, unlike other ionic liquids, synergistic formation hydrogen bonds between anions cations [Hmim]Cl hard segments uniquely diminishes size phase domains enhances dynamics within coating. endows capability to spontaneously, efficiently, repeatedly heal both mechanical chemical damage through migration polymer chains sites injury at ambient temperature. To highlight its practical applicability, this utilized fabricate transparent triboelectric nanogenerator (TENG). Compared conventional TENGs, proposed TENG not only exhibits superior antifouling self‐cleaning capabilities but also demonstrates an unparalleled capacity convert dripping alkanes, edible oils, polyols, water electric energy.
