Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="ppap201400145-sec-0001" sec-type="section"> <p>A transparent superhydrophobic surface on glass is prepared by a rapid single‐step method using a He, CH₄, C₄F₈ mixture plasma at atmospheric pressure. Water droplet contact angles and surface properties are investigated to analyze both chemical and physical characteristics of the plasma treated surfaces. As the C₄F₈ gas flow rate is increased in the He/CH₄ plasma, both advancing, and receding water contact angles are increased, while UV‐visible transmittance is degraded. By optimizing the gas mixture ratio, we find rapid deposition conditions for superhydrophobic formation without losing the visible to near‐infrared transparency of the glass. The chemical and physical mechanism responsible for hydrophobicity is also discussed through the investigation of chemical composition and surface morphology.<inline-graphic xlink:href="ark:/27927/pgh3xrpf68f" content-type="ppap201400145-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </sec> </abstract>
