Category — Superhydrophobic Coating

The superhydrophobiccoating.com team is glad to present you some nice videos from the application of our own superhydrophobic coating. The coating is produced by our team and has the advantage that is low cost and can be easily applied by brush or spray on various substrates (e.g. concrete, stones, metals etc).

The first video shows water droplets rolling off a tilted metal sheet. As you can clearly observe no trace of water is observed on the treated surface. The treated Zn sheet has become superhydrophobic and so it is fully protected against the corrosion caused by water.The Zn sheet is placed outside. The treated surface is left outside to test whether the coating will remain superhydrophobic after being exposed to sun, wind, rain, snow and atmospheric pollutants.

The second video shows the same coating applied this time on a wall. The coating was applied on the wall again by brush, about a year before the video was captured.

The upper part of the picture shows the untreated wall. The untreated wall is fully wetted. The rest of the wall which was protected with the coating is superhydrophobic. Consequently the wall is protected against water.

The same coating has been applied on various substrates like stones, concrete, glass, wood, fabric and the results were excellent. Every substrate became superhydrophobic!

The day you will not need to wash your clothes is coming closer. The researchers of the University of Zurich claim that they have discovered the perfect water repellent coat; the first super-hydrophobic coat. It is made of a fabric, which consists of polyester fibres coated with millions of tiny silicone filaments. It makes the water drops sitting on it, like the fakir on the spikes. The new super-hydrophobic fabric is durable at friction but it does not survive from the washing machine!

There many examples of superhydrophobic biological surfaces in nature. The ability of these surfaces to make water bead off completely and thereby wash off contamination very effectively has been termed the “Lotus effect”, although it is observed not only on the leaves of the Lotus (Nelumbo nucifera L.) but also on many other species, such as Tropaeolum majus L. (Indian Cress/Nasturtium) or Alchemilla vulgaris L. (Lady’s Mantle).
