摘要
The surface of medical polymethylmethacrylate intraocular lens was treated by F^(+) ion implantation at 80 keV with various doses.Hydrophobicity test showed that contact angle was increased from 68.5ºto 83.5ºwith increasing dose.No appreciable changes in optical transparency and tensile strength were observed.X-ray photoelectron spectroscopy and electron spin resonance analysis indicated that F+ion implantation broke some original O-containing groups to form some new C-F bond and radicals on the surface.
