The effect of surface properties of six types of biomedical materials on their blood compatibility was investigated in this study. The surface roughness of biomaterials was determined by confocal laser scanning microscopy (CLSM). The contact angle was observed by contact angle measurement (CAM). Then the surface free energy (SFE) and interfacial free energy (IFE) were calculated by the contact angle value based on the Owens-Wendt (OW) theoretical model and Young’s equation. Meanwhile, hemolytic assay was employed to evaluate the haemolysis. The experimental results showed that the greater roughness was, the greater contact angle would be; the less proportion of polar component in surface free energy (SFE) was, the lower haemolysis would be.
