Wetter Report: New Approach to Testing Surface Adhesion

Caption

Wetability gradient: Water sprayed on a glass slide coated with a nanostructured gradient wettability film using the new NIST technique illustrates the transition from (A) superhydrophobicity to (C) superhydrophilicity. The lower image shows the magnified image of the (A) hydrophobic to (B) transition wetting region. The pink dotted line indicates the border of the superhydrophobic region, and the yellow dotted region shows a hydrophobic 'sticky' region.
