Investigation of the surface properties of anti-adhesive antimicrobial coatings formed by ion-plasma technology on the surface of polyethyleneterephthalate and polytetrafluoroethylene

The paper is devoted to the problem of fight with biodestruction, the presence of which defines the duration of effective exploitation of polymeric materials and wares. The results showed the possibility of creating a field of transient processes that prevent the adhesion of microbial cells on the surface of polymeric materials. The specified transient area is the result of the optimum fluorine content in the film and the formed relief, which together ensure the absence of adhesion of microbial cells. The relief characteristic for the field of transient processes is different for polymers of various chemical structure. The study of antifungal activity showed that the areas of transient processes in different polymeric materials, ensuring the absence of cell adhesion of microorganisms and fungi, almost coincide.
