An algae-mussel-inspired underwater adhesive material was recently developed, which was activated by immersion in water. In this work, glycerol was used as a dispersant (replacing water as the medium) to disperse the adhesive and cohesive components; the resulting mixture was then applied for adhesive bonding underwater in order to improve the adhesives' stability and applicability. The dispersion of adhesive components in glycerol, the diffusive exchange of glycerol with water, and the development of adhesive bonding strength were all investigated through thermal characterization, optical imaging, and adhesive testing. The research findings enable the development of innovative processes for underwater adhesives that do not require chemical modification or difficult application steps.
