| Abstract: | In this paper,a functional graphene oxide was prepared with La3+ ions and the carboxylated graphene oxide sheet.The structure and properties of GeneO-La composite was characterized by Fourier transformed infrared specttroscopy(FT-IR) and trans mission electron microscopy(TEM);the functional graphene oxide was added to anticoagulation system and its effects on anticoagulant properties were studied.Results show that the La3+ ions have been coordinated on graphene oxide sheet layer.The blood compatibility of t... |
