Notes:
Silicone rubber substrates were irradiated at an acceleration voltage of 7 kV and a dose of1×1015 ions/cm2 by the simultaneous use of oxygen cluster and monomer ion beams, and then soakedin CaCl2 solution. Apatite-forming ability of the substrates was examined using a metastable calciumphosphate solution that had 1.5 times the ion concentrations of a normal simulated body fluid(1.5SBF). After the irradiation, the silicon oxide clusters (SiOx) were formed at the silicone rubbersurface. The hydrophilicity of the substrates was remarkably improved by the irradiation. Theirradiated silicone rubber substrates formed apatite in 1.5SBF, whereas unirradiated ones did not formit. These results suggest that the functional groups such as Si–OH and/or COOH groups inducedapatite nucleation in 1.5SBF
