A unique filtering nanomaterial has been created in Russia

The result of joint research by scientists from the Moscow Physicotechnical Institute and the Institute of Theoretical and Experimental Biophysics was a filtering nanomaterial with unique parameters. From an air stream containing particles with a diameter of no more than 0.3 micrometers, it “filters out” 98%. According to these indicators, the material surpasses existing analogues several times.

A similar result was made possible thanks to the electrospinning technology. The substrate of the future filter was "fired" from two sides: on the one hand, with a stream of dissolved polymer ejected by an electric field, and on the other - with sprayed ethyl alcohol, after which the resulting mixture of vapors settled on the substrate.

The result is transparent nanofibers with a density of 10-20 mg / sq. m. with cells no more than 15 nm. In practice, this means that breathing through such a filter is easier and cleaner.

Among the future "professions" of a unique nanomaterial is not only water and air purification. If you carefully examine the nanofibers under a microscope, you can see the "stuck" microorganisms.
