This adhesive, temporarily called hydrogel, works by harnessing electrostatic attraction between molecules to attach to the surface. Similar to the way we rub the surface of a balloon so that it creates an electrical charge and adheres to the ceiling.

This method is believed to be more tightly bonded and more durable than previous "waterproof" adhesives. These glues are like natural adhesives found in marine animals like galaxies. The drawback is that these glues often oxidize quickly, causing them to lose their adhesion.

Researchers at Hokkaido University (Japan) have developed hydrogels from polymer molecular chains, using electrostatic forces between these molecules to glue the adhesive onto negatively charged surfaces. These surfaces may be made of glass, stone and metal.

They also found a way for these electrical interactions to take place in a salt water environment like seawater.

The team tested the glue on a 500g glass block. After 5 seconds they were able to lift the glass block out of the water. In fact, the strength of the glue can reach about 60 kilo pascals - close to the pressure in the cabin of commercial aircraft.

Published in Nature on November 12, researcher Jian Ping Gong said the adhesive is easy to produce, low-cost and highly applicable. It can act as a super binder in an ion-rich environment like seawater, overcoming the problems of limited binders under the sea today.

"Hydrogel is highly applicable. It can be used to patch holes, leaks in the bottom of ships, bond sand to protect the marine environment, stick to concrete blocks built under the sea or salvage objects. from the bottom of the sea, "said researcher Jian Ping Gong.

The team also hopes that the invention will inspire world scientists to explore the same glue that works in other harsh environments.
