Most of the existing superclean has two serious drawbacks: they are usually made from harsh chemicals and difficult to “peeling”.

An international team of researchers has created a vegetable glue, which if necessary can easily “paste” and “delete”. Its active ingredient nanoparticles of cellulose, obtained from agricultural waste and the production of paper.

To glue the two surfaces, should be applied to them, nanoparticles add water, combine and heat. In the heating process the water evaporates, causing the particles to form strong relationships, becoming firmly attached to each other layers of the cellulose nanocrystals.

Glued just one drop of cyanoacrylate surface can withstand tensile stress up to 90 kg. However, if the two surfaces to pull to the side in opposite directions, is easy tear. In fact, the strength of the “broken” adhesive is one from the seventies, “working.” To remove the glue from the surface is very easy – just RUB it with your finger.

Currently, bonding of the surfaces takes about two hours, which can be reduced by increasing the heating temperature. However, as it turned out, the higher the temperature (over 50 °C), the smaller the final area of bonding.

Scientists hope that as the technology Matures, the superglue will find application in electronics or the manufacture of packaging containers, which then, after expiration date can easily be dismantled and disposed of.
