Abstract

We have developed photocatalytic patterning and tuning method of channel surface wettability using titania nanoparticles for microfluid control. Here, we present phase separation of segmented flow by using superhydrophobic/hydrophilic patterned surfaces prepared by the method. The phase separation mechanism, based on pressure balance among hydraulic pressures and Laplace pressure, is discussed.
