Having a phone that’s a fingerprint magnet may soon be a thing of the past. The solution, it seems, comes with the use of candle soot and silica using the right amount of temperature to put an end to fingerprint-tainted touchscreens.
A group of researchers from Germany have tested this combination and came out with impressive results: glass that was able to repel oil and grease. Imagine a smartphone and tablet that retains its glorious grease-free screen no matter how much you use it. Sounds too good to be true, right? These folks from Max Planck Institute for Polymer Research may have found the right tools and procedure to help ease our smudge-filled pain .
The test process involves holding a glass over a candle to produce the kind of soot the researchers wanted–sphere-shaped particles that measures around 30 to 40 nanometers. The tricky part involved removing the soot’s color and preventing it from being washed off. This is where a silica shell comes in handy and with the right amount of temperature, the soot’s color is gone leaving a pristine, clear screen.
But don’t throw your microfiber cloth just yet. While the new solution is a welcome development to making fingerprint-proof surfaces for touchscreens, it might take a while before the new procedure goes commercial.
