A team of researchers at Purdue University has developed a new biomimetic polymer adhesive that can stick underwater, overcoming the challenges of conventional adhesives that require a dry and clean surface. The adhesive is inspired by the way mussels can stick to rocks underwater, using a protein containing a unique amino acid called 3,4-dihydroxyphenylalanine, which is responsible for underwater adhesion. The researchers have created a polymer that contains this catechol group, making it possible to create an underwater adhesive that is three times more effective than conventional glues. The adhesive is made using a polymerization in suspension protocol, which uses water instead of organic solvents and reduces the risk of reaction runaways, making it a more sustainable and cost-effective option. This development has the potential to revolutionize industries such as marine construction, boat repair, and even medical devices. The researchers believe that their work demonstrates the power of biomimicry, which involves using nature’s solutions to solve human problems, and that it can be used to solve a wide range of problems in various fields.
