| Abstract: | The surface treatment of poly(ethylene terephthalate) (PET) and poly(vinyl chloride) (PVC) films in cold plasma over 1–15 min was carried out. It was found that the subsequent deformation of the films is accompanied by a special type of surface structuring that has been previously observed for polymer films with a thin hard coating. It was shown that unlike metal coatings, the thickness of the modified surface layer slightly depends on the time of treatment in plasma. The previously developed approach to analysis of the emerging patterns makes it possible to evaluate the stress-strain properties of the coatings. It was first revealed that the tensile strength of the modified layer produced in PET by plasma treatment is ∼12.3 MPa and its elongation at break varies from 20 to 90%. The differences in the properties between the plasma-modified surface layers of the polymer and the metal coatings studied earlier are discussed. |
