Abstract

The risk of clot formation in blood-contacting devices is a significant concern. Therefore, development of biomaterials with improved hemocompatibility is a clinical need. Altering surface properties is an effective strategy to enhance the hemocompatibility. We have investigated the effect of hydrophilic polyethylene glycol (PEG) amount over the hydrophobic polycarbonate (PC) on hemocompatibility of polyurethanes. The presence of PEG on the surface was evaluated using ATR, AFM, and WCA. At above 20% of PEG to PC ratios, exhibit zero WCA, considerable improvement in hemocompatibility, was achieved. The results indicated the synthesized PUs could be used as coatings of cardiovascular devices. © 2020 Taylor & Francis Group, LLC.
