Abstract

The present invention relates to a non-woven filtering material of a high filtering efficiency, modified by ZnO nanorods, for use in filtering systems and devices for purifying liquids and/or gases, in particular in air and water filters and in coalescers. In the present invention, a new solution consists in that on the surface of the fibers of the filtering material of a thermoplastic polymer produced by the melt blowing technique (melt-blown fibers), having controlled fiber diameter, preferably in the range 0.1 - 10 μπ\, forming a. non-woven, polymer structure of the filtering material, it is developed a palisade of ZnO nano-protrusions in the form of ZnO nanorods having diameters, preferably in the range 5-100 nanometers, the heights, preferably, in the range 50-500 nanometers and the distance between adjacent nano-rods spaced on the surface of the fiber preferably 30-1000 nanometers. The invention also provides a method for manufacturing such non- woven filtering material and a use of the inventive filtering material in filtering cartridges.
