When you try to use glue in water, even the strongest glue is useless. But aquatic shellfish can hold on to the rocks and avoid predators taking them away. It is clear that nature has found a way to make it work under water, and now researchers may have discovered the secret.
In a new study published in the “applied materials and interfaces” Journal, researchers from the Purdue University described a new bionic glue and its inspiration is from mussels can be firmly adsorbed on the rock phenomenon, even in a straight water trying to make their efforts.
Originally, the mussel was able to adhere to the surface of other things, even under water, because they use a small hair covering natural rubber, natural rubber and rich in protein and amino acids of the dihydroxy phenylalanine (DOPA). When most of the binders react with water, the compound catechol, which is not found in. Instead, they are able to stick to their duties and glue them to other materials. When the researchers added these amino acids and other mussel proteins to their artificial polymers, they succeeded in creating one of the most powerful underwater glues in history.
Surprisingly, the binding test showed that the new binder (polyester fiber) was 17 times more powerful than the natural rubber used by mussels. However, the researchers do not think they are stronger than the natural mother. They think the mussels themselves limit the size of the binders they use, so they can be more easily removed when they need to move.
This improved, inspired by the mussel, can bring about new changes in car manufacturing and housing construction. It can also be used in underwater repair, whether temporary or permanent repair. It’s also possible that it could be a more convenient tool, so you don’t have to take a pool of water for a small crack in the pool
Even the strongest artificial glues are completely useless when you try to apply them underwater, but somehow shellfish are able to hold fast to rocks to deter predators from trying to carry them away. Clearly, nature has already figured out how to make glues that work underwater, and now researchers may have discovered the secret.
In a paper recently published in the journal Applied Materials and Interfaces, researchers at Purdue University detail a new ‘biomimetic’ glue, inspired by the observation that shellfish like mussels stick incredibly well to rocks, despite the crashing ocean constantly trying to undo their efforts.
