Abstract
We describe our investigations of the surface physicochemical properties of polyvinyl alcohol modified by silver, argon and carbon ion implantation to doses of 1Â ÃÂ 1014, 1Â ÃÂ 1015 and 1Â ÃÂ 1016Â ion/cm2 and energies of 20Â keV (for C and Ar) and 40Â keV (for Ag). Infrared spectroscopy (IRS) indicates that destructive processes accompanied by chemical bond (CO) generation are induced by implantation, and X-ray photoelectron spectroscopy (XPS) analysis indicates that the implanted silver is in a metallic Ag3d state without stable chemical bond formation with polymer chains. Ion implantation is found to affect the surface energy: the polar component increases while the dispersion part decreases with increasing implantation dose. Surface roughness is greater after ion implantation and the hydrophobicity increases with increasing dose, for all ion species. We find that ion implantation of Ag, Ar and C leads to a reduction in the polymer microhardness by a factor of five, while the surface electrical resistivity declines modestly.
