Abstract
Fluorinated low energy polymer surfaces are provided by fluorinating a hydrocarbon polymer with ions or radicals of fluorinated species in a cold plasma.
Claims9
The process for fluorinating a hydrocarbon or amide polymer to form a low energy fluorinated polymer surface substantially free of oxygen which comprises contacting a polymer with a cold plasma comprising ions and/or radicals of fluorinated species selected from the group consisting of fluorine, tetrafluoromethane, hydrogen fluoride, hexafluoroethane, sulfur hexafluoride, difluoromethane, trifluoromethane, and mixtures thereof, under conditions to effect substantially complete fluorination of the surface of said polymer without substantial degradation of said polymer.
