| Abstract: | Data on the strength of coatings based on noble metals (Pt, Au) deposited onto PET films by the method of ionic plasma sputtering
are analyzed. In addition to precipitation of the metal, this mode of deposition is accompanied by modification of the surface
polymer layer due to its interaction with plasma. As a result, a complex three-layered structure near the polymer surface
forms. A new method for estimating the strength of coatings deposited onto polymer supports is advanced. This method makes
it possible to analyze stress-strain characteristics of the three-layered systems that emerge owing to deposition of nanoscale
layers of noble metals on polymer films via ionic plasma sputtering. The proposed relationships are in fair agreement with
the experimental data. |
