Resumen:
The surface free energy (SFE) of solids are usually calculated using theoretical models and experimental measurements of contact angle. In the present report the following three models have seen used in the calculated of SFE of titanium dioxide; Geometric Mean, Harmonic Mean and Lifshitz-van der Waals/Acid-Base models. The results show that the SFE and its components depend on the model as well as the liquid employed in the measurement of contact angle. Considering that the SFE is strongly related of the surface-blood interaction and the haemocompatibility of the material, the contact angle measurement and proper application of theoretical model assumptions are critical for reliable predictions of haemocompatibility.
