A newly developed smudge repellent coating may save you the trouble of cleaning your smartphone.

Touch smartphones and tablets are all the rage these days, but there’s no denying the fact that working with them intensively makes a real mess out of their front glass panels. Some manufacturer apply some kind of smudge-resistant coating to their screens to make cleaning easier, but it’s not a perfect solution.

Scientist from the Max Planck Institute for Polymer Research in Mainz have stepped up with a claim that they have developed a new smudge repellent coating that could eradicate the problem altogether.

The new coating consists of candle soot, coated with a 25nm-thick silica shell and calcinated at 600°C in order to become transparent. After silanization, the coating becomes superamphiphobic and remained so even after its top layer was damaged by sand impingement.

In short, the new coating should be perfectly smudge (and oil) proof. According to the researchers, the coating itself should be easy to manufacture, so applying it to smartphones and tablets shouldn’t lead to a significant increase in the production costs.

Are you happy about the seemingly imminent end of the smudgy screen era? Or are you one of those guys that couldn’t care less about a few fingerpints on their smartphone display?

Good stuff. Will probably become standard on phones. And then a few years from now, Apple will be suing anyone who uses it, claiming they invented the stuff :D

That will be cool. I started using the little cloth they use for your glasses on my ipod touch and it works perfectly.
