Drop motion on an inclined plane and evaluation of hydrophobic treatments to glass

摘要: Abstract Hydrophobic and anti-rain surface treatments are increasingly used to treat various glass articles such as windscreens, windows, headlamps, wing mirrors, optical lenses, sunglasses, etc. To evaluate the efficiency durability of these treatments, we determine smallest volume or critical sliding volume, V c , a water drop able slide down spontaneously under gravity after having been deposited on vertical treated, surface. The property repellency is considered be better when smaller. In this paper, new simplified theory describe capillary force retaining drops an inclined plane proposed verified practically. experimental method allows us compare commercial Corning Inc. proprietary hydrophobic treatment for glass, both being based silicone derivative chemistry. As defined in appears practical parameter which may...
