The effects of F+ ion implantation on the composition and the structure of oriented polypropylene were studied by optical methods and the Rutherford backscattering (RBS) technique. From the measurement of the contact angle, it was found that the polar component of the surface energy increases with increasing ion fluence. The spectroscopic measurements confirmed the formation of conjugated double bonds and C=O groups in the implanted polypropylene, but not the presence of C-F groups. The oxygen contamination of the polypropylene surface layer was observed in RBS measurements.

SYNOPSISThe creation of oxidized structures and double bonds in polyethylene (PE) and polypropylene ( P P ) samples implanted with P + ions was studied. The surface polarity and the electrical conductivity of the ion-implanted polymers were also examined. As a result of the ion implantation, the polymer macromolecules are broken up and the material is degraded. An oxygen penetration into the radiation-damaged polymers is also observed, with PE being more vulnerable to the oxidation. The ion-implanted PP exhibits higher surface polarity and sheet conductivity compared to that of PE. 0
