Optical properties of antimicrobial barrier layers based on polyethylene terephthalate with a nanostructured surface

详细

The optical properties of nanostructured barrier layers based on polyethylene terephthalate formed by ion technology and their resistance to biodegradation are discussed. The influence of the surface energy and relief parameters on the antimicrobial activity of nanostructured barrier layers is established. The study of reflection spectra demonstrates the fine structure of spectral lines apparently connected with the scattering of electromagnetic radiation by charged centers. These centers are formed on a nanostructured polymer surface after ion-plasma treatment as well as upon the deposition of α-C:H films which are known as electrets with a large number of broken bonds.
