摘要

<正> This paper reported the research results concerning the surface characterization ofpolystyrene-graft-w-stearyl poly（ethylene oxide）（PS-g-SPEO） by means of XPS

contactangle measurement and TEM

and its in vitro blood compatibility assessment by measuringthe plasma recalcification time （RT） and partial thromboplastin time （PTT）. The XPSresults demonstrated that the surface and bulk composition of the PS-g-SPEO graftcopolymers differ remarkably from each other

and that SPEO component was constantlyenriched at the copolymer/air interface. Contact angle studies indicated that the surfacewater wettability can be adjusted effectively by changing the composition of the copolymer.PS-g-SPEO graft copolymers can undergo microphase separation as clearly illustrated byTEM photographs. The relationship between the surface properties of PS-g-SPEO graftcopolymer and its blood compatibility was also discussed.
