Created tissue, which can not stain

Australian scientists have developed a new fabric cover, which does not lend itself to pollution: it actively pushes away dirt, strong acids, grease and other contaminants.

Tong Lin, together with his colleagues from the University of Dickens in Australia explained that when creating a new type of fabric they used the method of layered assembly that allows you to get a coatings and films for drug delivery systems, sensors, and other tissues and products. This technology involves the alternation of negatively and positively charged layers of material held together due to the attraction of opposite charges. Such coatings can be created for different purposes, selecting a specific composition of each layer for each case.

As usual, without the drawbacks too, was not. Multiple-film layers are unstable and eventually disintegrate. Therefore, Australian researchers began to develop a method of stabilizing films by UV irradiation to create a "superhydrophobic" coating that uses the surface tension force to repel grease, water, dirt and other materials.

As a single layer of silica nanoparticles researchers used polymer coated and terminated azido. They are UV active reagents and promote crosslinking between polymer strands with a cloth. Get a superhydrophobic material handling ftoralkilsilanami helped.

The new coating was laboratory testing, during which it was proved that, if put it on a cotton fabric, the fabric will repel acid, water and organic solvents. This coating clings to the cloth, proof of which is its safety, even after fifty washes.
