Abstract Underwater adhesives serve as essential functional materials with extensive applications in underwater robotic operations, submarine pipeline installation and maintenance, maritime defense projects, and marine engineering infrastructure. However, the construction of robust and reliable underwater bonding interfaces is severely constrained by substrate surface hydration layers and limited interfacial interaction strength, which has become a core bottleneck restricting the development of high-performance underwater adhesives. Herein, we use in situ polymerization and particle reinforcement to enhance adhesion strength: An underwater adhesive is prepared by reacting bis(3-aminopropyl)-terminated polydimethylsiloxane with hexamethylene diisocyanate in the presence of Ca(OH)₂, which acts as a precursor… More >
