Scientists develop new solution to keep glass clean and fog-free

Deposition of dust and formation of fog on the glass is a very common problem that is faced in almost every work like driving, skiing etc. Jeffrey Youngblood, an associate professor of materials engineering at Purdue and his associate have found a solution to this problem. They have developed a glass coating that will prevent the fog formation and make it easy to get rid of dust and greasy materials. This coating includes of two layers the bottom layer, consisting of a water-loving solvent called polyethylene glycol, pulls water in and forms a smooth and clear layer on the glass surface, the second layer contains a Teflon-like molecule that is large enough to prevent oil from passing through.

Mainly this layer adheres the property of glass to attract greasy materials like oil and acts as a filter. The coating is likely to work on plastic lenses as well. The coating as some additional advantages as it can self clean itself reducing some work for you to clean the glass. The coating could also be used as a water filter as it can retain 95% of the greasy materials on the top most layers and let the filtered ware pass to the next layer. But unfortunately you may have to wait for another few years to use this material, it is predicted that the material will we available in form of a solution that could be sprayed onto bathroom mirrors and sunglasses every couple of weeks to keep them clean and fog-free.
