Abstract: Ionic gels have emerged as a promising class of materials for underwater adhesion, offering unique advantages to address the critical challenges of durability and adhesion performance under demanding wet conditions encountered in marine engineering, biomedical devices, and routine maintenance. This review systematically examines the recent progress in utilizing ionic gels as underwater adhesives, focuses on elucidating their underlying adhesion mechanisms, key performance characteristics, and diverse application prospects. By analyzing current research findings, this work summarizes the state of development, identifies prevailing challenges, and outlines future research directions for ionic gel-based underwater adhesives. The insights provided aim to serve as a theoretical foundation and practical reference for the advancement and application of next-generation underwater adhesive materials.
