Poly(vinyl alcohol), an inherently amphiphilic material, can act as a superhydrophobic surface when deposited as nanofibers on an aluminum oxide membrane (see picture). The arrangement of the hydrophobic and hydrophilic functional groups, both in the surface and within the interior of the material, has a marked effect on surface activity.
