Surface Characterization of Asymmetric Bi-Soft Segment Poly(ester urethane urea) Membranes for Blood-Oxygenation Medical Devices
Figure 4
Correlation between water contact angle and maximum zeta potential observed in zeta potential versus pH plots at alkaline pH values (NaOH addition, 10−3 M KCl background electrolyte) for the blood-contacting surface of the PEUU membranes.
