Abstract： Surface blood compatibility of ion beam and plasma treatment on polyetherurethane has been studied. O+ implantation was performed at 80keV with various doses. O2 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.
