摘要:
The processes in polymer films based on polypropylene containing fluorinated additives during modification of films in corona discharge plasma are studied. The chemical composition, relief, adhesion and deformation properties of the film surface before and after modification in plasma were studied using the methods of X-ray photoelectron spectroscopy and atomic force microscopy. It has been established that in films under the influence of corona discharge plasma migration of the fluoropolymer additive to the surface occurs. In this case, the chemical composition and structure of the film changes, and local structures containing oxygen, fluorine and carbon atoms are formed on the surface. Local structures have an electrical resistance that is different from the electrical resistance of the surface of the original film. Plasma modification leads to an improvement in the elastic and adhesive properties of the polypropylene film surface.
