摘要：Underwater adhesives hold significant relevance in daily life and applications. Despite great efforts, the development of high-performance underwater adhesives through a simple and effective method remains a difficult challenge. Herein, a high adhesion and environmentally stable polyurethane underwater adhesive (DAP-PU) was developed based on rosin with a hydrogenated phenanthrene ring skeleton to design hydrophobic domains, and combined with multi-strength hydrogen bonding interactions to construct "polar hydrophobic domains". DAP-PU exhibits a strong underwater bonding and adhesion performance on various substrates (steel, aluminum, PMMA and glass) in harsh aqueous conditions (1 M NaCl, pH 5 and seawater), with the highest peel and shear strengths on stainless steel substrates reaching 12.88 N cm?1 and 1.7 MPa, respectively. In addition, DAP-PU can be used in various fields such as underwater sand consolidation, underwater sealing and repair. ? 2025 The Royal Society of Chemistry.
