Power up new type of glue will harden wet things can also stick

The glue can work in a damp environment, has infinite possibilities in various areas, such as nursing and ship maintenance, and so on. Previously, someone has already tried to simulate the adsorption capacity of the mussels to boat on the docks, while those from Singapore Nanyang Technological University’s team from a different angle, and developed a power up before the glue hardens.

In the future, doctors can use glue to the biocompatibility of patient tissue to bond together, just 1–2 minutes for the time required, and traditional ways of stitching usually 15–20 minutes. This new type of glue can significantly enhance the efficiency of the doctor’s surgery.

Nanyang Technological University materials science and engineering, Professor Terry Steele is the Chief Scientist of the research team, he pointed out that most of the glue in a humid environment is not normally available, like tape can’t adhere to wet the surface, rather the reason is that the adhesive on the water surface.

Regular glue after contact with the moisture in the air will harden, and epoxy resins that are used in our mobile devices needed in 150 degrees Celsius temperatures and heat, or use two different chemical substances are mixed together, obviously, none of these methods in a wet environment.

Steele and his team after a year of research, succeeded in making a new adhesive, it can work in a humid environment, such as water and the human body. Researchers said: “we must find a way to make the glue hardened and is not affected by environmental conditions, so power is the best way for us. ”

Researchers used carbon-containing dendritic polymers developed a water gel, when it comes to current time, these will be attached to the surface of the polymer, polymer adhesion level determines the rigidity of glue. They said the hardness of this new type of glue can be changed by adjusting the time, able to adapt to different usage scenarios.

Steele said: “for example, when bonding metal plates in the water, we hope to enhance the rigidity of glue to keep it longer, and in terms of health care, we want to glue a rubber-like elastic, so it won’t cause any damage to the surrounding soft tissue. “In addition, this new type of glue also has a reversible capacity, namely the withdrawal of adhesion of the glue. When we ship dismantling parts when the reversibility will greatly enhance the work efficiency of dismantling becomes much simpler for bolts and nuts.

Currently, Terry Steele and his team are trying to reduce the time needed to harden the glue, they hope this time can be reduced from half a minute to a few seconds. Not only that, but they will be for further study on the reversibility of the glue.
