摘    要:The purpose of this paper was to enhance blood compatibility of polyethylene (PE) film. PE film pretreated by argon plasma was subjected to ultraviolet (UV) -induced graft polymerization with Acrylic acid(AAc) (AAc-grafted PE films, PE-g-PAAc) without photo-initiator, then heparin was covalently immobilized on the PE surface (PE-g-HPAAc). The surface properties and microstructure of PE-g-PAAc and PE-g-HPAAc were studied by static contact angle measurement, atomic force microscope (AFM), X-ray photoelectron spectroscopy (XPS) and Attenuated total reflectance Fourier transfer infrared spectroscopy (ATR-FTIR). It was confirmed that AAc and heparin were successfully immobilized onto the surface of PE film. Results of platelet adhesion experiments indicated that the antithrombogenicity of the modified PE film was remarkably improved.
