Successfully developed gravel glue that breaks down is sticky

This glue can dry at normal conditions and become sticky when there is a collision.

Made of gas seal when broken

Researchers from the Osaka Institute of Technology (Japan) have developed a gravel shaped pebble . The special feature of this glue is its ability to stick only when crushed. Under normal conditions they are unconformable pebbles.

The secret is to keep the glue from sticking to every surface it touches, thanks to a thin coating of calcium carbonate nanoparticles. Inside the shell is a layer of liquid rubber adhesive. When these stones are impacted by external forces, the inner bonding layer is released and turns them into a fairly solid glue.

Thanks to the ability to dry under normal conditions and only to become adhesive when the effect of this particular adhesive can be easily applied in many situations when the environment is cramped and objects need to stick to the image. weirdness.

Researchers believe that this type of glue will be especially useful in the production of cars, electronics such as smartphones, computers, etc.

Unlike other adhesives , they will become solid at room temperature and, in particular, need not be heated or melt to form adhesives. Moreover, they have much better adhesion than other types of glue such as memory stick or adhesive tape (pressure sensitive adhesive). Especially the adhesion on rough surfaces such as wood is quite good.

Special adhesive that can seal the gas is broken.

The research was published in the journal Materials Horizons.
