摘要
Surface blood compatibility of ion beam and plasma treatment on polyetherurethane has been studied.O^(+)implantation was performed at 80keV with various doses.O_(2) plasma treatment was carried out at 100 W with various exposure times.The results indicated that surface anticogulability was enhanced in varying degrees and anticalcific behavior was not decreased.X-ray photoelectron spectroscopy and electron spin resonance analysis showed that the two methods not only broke some chemical bonds,but also produced some new N-O and C-O bonds and radicals in the surface,which affected the surface biomedical behavior.
