| Shellfish are the natural experts of underwater adhesion. Organisms like mussels, barnacles, and oysters attach to underwater rocks with ease, yet man-made adhesives struggle significantly in wet environments. When submerged, glue interacts with water molecules prior to attaching to a surface. These interactions reduce the strength of the adhesive. However, the common blue mussel attaches itself via a mixture of atypical proteins cross-linked into an adhesive. By understanding this biological phenomenon, a similar, more effective product can be produced. A Purdue University researcher has developed a polymer mimic of mussel adhesives with exceptional underwater bonding characteristics. The researchers examined adhesive strength of a catechol-polystyrene polymer as a function of polymer molecular weight and composition, resulting in a polymer composition that proves to be the strongest underwater adhesive compared to commercial marine glues. The glue's adhesion is stronger in saltwater versus deionized water, making the polymer a viable marine adhesive. Advantages: -Stronger than natural mussel adhesive -Stronger than commercial marine adhesives -Stronger in saltwater Potential Applications: -Underwater adhesive -Construction and repair in marine and wet environments Related Publications: J.
