We are exploring the temporal dependence of the
electrokinetic response of hydrophobic surfaces.
Recent observations show that hydrophobic
surfaces develop interfacial voids. Coincident
with these voids is a long time scale change in
the electrokinetic response of the system. We
are investigating these phenomena with atomic
force microscopy and time-resolved electrokinetic
characterization.
