Antiadhesion Fluorocarbon Coatings With Induced Surface Charge for Protection Against Biodegradation

Abstract

This paper analyzes the results of studying the antimicrobial properties of nanostructured fluorocarbon films deposited on polymers by ion-plasma technology. For the first time, the dependence of the surface charge and antimicrobial properties over time was established. As the negative charge drains, the number of colonies of the studied bacteria and fungi increases. Fluorocarbon films were formed using a two-component gas mixture (CF<sub>4</sub> + C<sub>6</sub>H<sub>12</sub>) with different ratios of components. Antimicrobial activity on fluorocarbon coatings is maintained for 12 months.
