摘要：

Surface modification behaviors of glass-like carbon (GLC) by oxygen ion implantation were studied at the ionic doses of 1, 10 and 100 x 10(14) ions/cm(2). Formation of bank network at the GLC surface, following initial smoothing, was observed with atomic force microscopy (AFM). At the same time, Friction coefficient and surface roughness decreased at the ionic dose of 1 x 10(14) ions/cm(2), but increased again at higher doses. Increase in surface disorder at lower ionic dose and change to amorphous at higher doses were detected with Raman spectroscopy. As O/C ratio measured with X-ray photoelectron spectroscopy (XPS) increased with the ionic dose, the contact angle of the GLC surface with water decreased. The most biocompatible GLC surface was obtained at the dose of 1 x 10(14) ions/cm(2). (C) 2009 Elsevier B.V. All rights reserved.
