Abstract

Layers of copper sulfides, Cu_xS, on the surface of a polypropylene film were formed by the sorption–diffusion method using two reducing agents – hydroquinone and hydroxylamine sulfate. The formed copper sulfide layers were investigated by UV/VIS, X-ray diffraction (XRD) and water contact angle measurements (WCA). The investigations confirmed that a layer of nonstoichiometric copper sulfide was formed on the surface of the polypropylene film. The water contact angle measurements revealed the change in adhesive properties of the samples after each treatment stage.
