Abstract:
The invention relates to a method for the modification of the surface of shaped parts made of plastic by treatment with a gas mixture which comprises fluorine and oxygen. The surface tension of the modified surface of the shaped part is more than 25 mN/m greater than that of a surface comprising non-modified plastic material. The ratio of the partial pressure of fluorine to the partial pressure of oxygen is 1:10 or lower and the shaped part has a fluorine occupancy of less than 0.5 μg/cm2 as a result of the treatment.
