Surface Treatment of Fluorinated Biomedical Devices

摘要

A method for treating the surface of a fluorinated biomedical device is provided comprising the steps of (a) plasma treating the fluorinated biomedical device with a hydrogen-containing atmosphere to reduce the fluorine or C-F bonding content of the fluorinated biomedical device; and (b) subjecting the hydrogen plasma treated surface to a plasma-polymerization reaction in a hydrocarbon-containing atmosphere to form a polymeric carbonaceous layer on the surface of the biomedical device.
