Contact angle measurements for the outer side of the PAM as a function of pore diameter for various membrane thicknesses: 1 (blue diamonds) – 28 µm; 2 (red squares) – 45 µm; 3 (green triangles) – 65 µm; 4 (purple circles) – 75 µm. The inset shows an SEM image of the outer surface. The black dotted line is a polynomial fit shown as a guide to the eye for all data sets.
