Abstract
The invention relates to a method for modifying at least a part of the surface of a fluorine-containing plastic, which comprises making the surface hydrophobic by 1) ion-etching the plastic surface; and 2) subsequently treating the plastic surface with flow discharging. The invention also relates to a fluorine-containing plastic having a surface which is at least partially hydrophobe-modified by ion-etching followed by glow discharging, and to materials, such as bio-materials, in which the plastic is incorporated.
