摘要
Commercial, purified PVC films were surface-modified by Ar and mixed Ar + O-2 RF plasma at atmospheric pressure. The change of surface properties was monitored by contact angle measurements. Both modifications cause surface oxidation of PVC films, which is connected with the formation of functional groups enhancing polymer wettability. This process is very fast and efficient in mixed Ar + O-2 RF plasma but relatively slower during PVC exposure to Ar. The interface reactions of sputtered Ti with PVC have been studied using high resolution X-ray diffractometer and X-ray photoelectron spectroscopy. The reactions of Ti with PVC lead to the simultaneous formation of TiCL2, TiC and Ti-oxide. (C) 2003 Elsevier Science B.V. All rights reserved.
