Behavior Of Polymeric Matrices Containing Silver Inclusions, 2 - Oxidative Aging Of Nanocomposite Ag/c:h And Ag/c:h:o Films

摘要

Nanocomposite Ag/C:H and Ag/C:H:O films were deposited by means of an unbalanced magnetron operated in a gas mixture of argon, hexane, and carbon dioxide. Infrared spec-troscopy was employed to investigate the deposited layers in situ and to monitor film aging.rnUsual CH_2/CH_3 stretching and deformation bands dominate in the infrared spectra of as-grown Ag/C:H films. Oxidation processes observed by FTIR as an evolution of absorption bands caused by hydroxyl, carbonyl, carboxy-late, and carbonate groups depend considerably on the content of the metallic phase. It has been shown that the metallic particle surface is very important for the oxidation processes.
