Abstract

Using X-ray photoelectron spectroscopy, the change in the chemical composition of the polyketon films surface as a result of treatment by the low-pressure direct current discharge was studied. The films were placed at the anode and cathode, and filtered atmospheric air was used as the working gas. The formation of a significant amount of oxygen-containing groups on the polymer surface was shown. Using atomic force microscopy, it was found that plasma treatment leads to a significant increase in the surface roughness of the films. Such changes improve the contact and adhesion properties of polyketon films.
