Hollow fiber membranes with satisfied blood compatibility and antibacterial property are desired in blood purification. Herein, a series of heparin-like copolymers of poly(methyl methacrylate-vinyl pyrrolidone -sodium styrene sulfonate-sodium acrylate) (poly(MMA-VP-SSNa-SA)) were synthesized by free radical solution polymerization. The mixture was directly blended with polyethersulfone (PES) solution to prepare hollow fiber membranes. The membranes were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Blood compatibility of the hollow fiber membranes was evaluated via protein adsorption, platelet adhesion, clotting time, and hemolysis assay. Besides, Ag nanoparticles were immobilized onto the hollow fiber membranes efficiently by a simple and green method, and the antibacterial property and blood compatibility of the Ag-loaded membranes were then investigated. The results indicated that the approach towards blood compatible and antibacterial hollow fiber membrane is efficient and flexible for the modification for membrane materials.
