Marine Adhesives - Prof. Jonathan Wilker - CPS Talk 2021

Imagine trying to live at the beach, constantly being pounded by waves. Nature has developed intriguing classes of adhesives for allowing mussels, barnacles, and oysters to stay in place. By contrast, consider all of the adhesives that you can buy at the hardware store. None function well in water. How do these animals stick in such an environment? What can we do with this technology once we understand it? Our group is working to uncover these secrets of how shellfish. We are then using insights for the development of biomimetic materials. In doing so we have created new materials that can bond more strongly than Super Glue. These synthetic polymers also appear to be one of the strongest underwater adhesives seen to date. Surgical connection of tissues may be less traumatic when we can transition from sutures and screws to biocompatible adhesives. Replacing carcinogens in plywood and fiberboard adhesives will have significant health impacts. Other applications of focus include creating debonding adhesives for electronics to enable recycling, making replacements for the toxic glues used in cosmetics, and developing underwater adhesives to aid coral reef restoration efforts. This talk was delivered by Professor Jon Wilker from Purdue University to the audience of the public, CPS members, and UCL staff and students on the 2nd February 2021.
