The change of contact angles as a function of contact time. The original PVDF membranes (Solecta PVDF 700) were used as a control for the functionalized PMAA-PVDF membranes (12.1 wt% PMAA). The membranes were immersed at target pH and then dried under a nitrogen flow before the contact angle measurement.
