ABSTRAKT

Track membranes (TM), obtained by irradiation of polymeric films by a beam of high-power heavy ions and subsequent etching of the tracks of these particles right to the formation of through pores, have taken an important place among the filtering elements used. Due to a number of properties, such as the small thickness and the high uniformity of pore sizes TMs have low resistance to a flow of a filtered medium, high selectivity of separation, low adsorption of the dissolved substances, and the ease of regeneration. Due to all these properties TMs are widely used in medicine, biotechnology, microelectronics, and some other areas of technology.
The paper presents the results of the study of the physicochemical properties of the surface of polyethylene terephthalate track membranes (PET TM) with a nanostructured surface formed by ion-plasma technology, in particular, the topology of the surface, relief parameters, the total surface energy and its polar and dispersion components, as well as the antimicrobial activity of the PET TM surface in relation to museum strains of microorganisms and fungi. The correlation between them has been obtained.
