Scientists have developed the technology to create polymer coatings that will protect materials from wetting and damaging effects of microorganisms.
Researchers from the Volgograd state technical University has set itself the task of producing such coatings that are completely waterproof (superhydrophobic) or absorbent (superhydrophilic) water. Thus the production process should be inexpensive and available in Russia.
“For the production of such coatings, we have developed new polymers that make them more sustainable, explains head of project, candidate of chemical Sciences Victor Klimov. – They change the surface properties of a material without affecting its settings in General, and promising, for example, to separate oil-water emulsions and make the surface of the subject’s ability to cleanse itself”.
for example, the coating can be applied to the inner surface of the sewer pipe, in which water flows with different compositions. Protective film will not form deposits on the metal.
If we talk about self-cleaning, there will be a similar effect. For example, if the drippings on a waterproof surface, they will spread out, preventing contamination.
development of the Volgograd scientists will expand the range of application of the usual materials. Thus, the waterproof coating will be able to perform de-icing, anti-corrosion and antivibratory functions. That is, will prevent the formation of water film and prevent icing.
This protection is relevant to many sectors of the economy – in energy, aviation, telecommunication systems, housing and communal services, as well as when working in the Arctic zone, because the modern methods of struggle against the same ice is ineffective.
Grafted polymer in the coating to minimize the contact with water and aggressive environments. For example, will not allow microorganisms and algae to multiply on the subjects on which they are applied.
– it is Known that wood very quickly swells from moisture, but with our composition on the surface it can swim in the water at least three months, and nothing happens, as confirmed by experiments, – said Victor Klimov.
the Work of scientists will help to solve the fundamental problems of process control wettability of the surface of almost any solid.
Created with Volgograd copolymer coating can be used, including satellite antennas, and metal poles and power lines, the production of water resistant fabrics and filter materials for the separation of oil-water emulsions.
– For example, because of an accident of oileprovide on the surface of the pond came the oil slick. Put in a spot of material modified with our polymer, and it will absorb all the oil, – says the scientist.
the Project for the Volgograd chemists received a grant from the Russian science Foundation in the framework of the presidential program.
