Arikel mit plasmapolymerer Beschichtung und Verfahren zu dessen Herstellung

摘要

The invention relates to an article that comprises a substrate, and a plasmapolymer coating applied across the surface of the substrate and comprising silicon, oxygen and carbon. An analysis by ESCA gives an amount of substance ratio for O:Si greater than 1.25 and less than 2.6, and the amount of substance ratio for C:Si is greater than 0.6 and less than 2.2. According to a preferred embodiment, the coating contains, based on its total atom content without hydrogen and/or fluorine, a minimum of 22 and a maximum of 27 atomic percent of Si, a minimum of 25 and a maximum of 50 atomic percent of O, and a minimum of 25 and a maximum of 50 atomic percent of C.
