Peyman and Brylee collaborated with George to explore the effects of catechol content, molecular architecture, and solvent quality on mussel-inspired pressure-sensitive adhesive (PSA) adhesion and cohesion measured in a surface forces apparatus. Their findings demonstrate that the influence of catechol content depends on the choice of solvent and that adhesive performance is dictated by film composition rather than molecular architecture. The results also highlight the importance of electrostatic and hydrophobic interactions for adhesion and cohesion in aqueous environments. Together, our findings contribute to an improved understanding of the interplay between materials chemistry, environmental conditions, and adhesive performance to facilitate the design of bioinspired wet adhesives.

Congratulations to former group members Peyman and Brylee on the publication of their collaborative work with George Degen on mussel-inspired PSAs
