A method of decreasing a water contact angle and/or increasing a surface energy of a liquid is disclosed herein, the method comprising exposing the liquid to a plasma treatment. Further disclosed is a plasma-treated liquid exhibiting a decreased water contact angle and/or increased surface energy, compared to the water contact angle and/or surface energy, respectively, of a non-treated corresponding liquid. Methods for combining a first liquid and a second liquid, or for enhancing an adhesion between a liquid and a surface of another substance, the methods comprising exposing a liquid to plasma treatment, are further disclose herein, as well as a method of predicting an apparent contact angle of a liquid droplet on a surface of a substance.

Plasma treatment of liquid surfaces

A method of manufacturing a multiscale (hierarchical) superhydrophobic surface is provided. The method includes texturing a polymer surface at three size scales, in a fractal-like or pseudo-fractal-like manner, the lowest scale being nanoscale and the highest microscale. The hydrophobic polymer surface may be converted to hydrophobic metal surface by subsequent deposition of a metal layer onto the polymer surface.
