Polypropylene (PP) was exposed to various fluorine-gas mixtures and the flu
orinated PP surfaces were characterised by means of X-ray photoelectron spe
ctroscopy, Rutherford backscattering, attenuated total reflectance infrared
spectroscopy, solid-liquid contact angles and thermogravimetric analysis.
The surface wettability and surface tensions of PP, as functions of fluorin
ation and oxyfluorination times, were also determined and discussed. (C) 19
