Glass smartphones have a serious flaw — they are in seconds covered with fingerprints. Samsung found a solution — patented glass that repels grease and water.
If conventional hydrophobic material repels water drops which fall at any angle up to 90 degrees, the new development is a superhydrophobic polymer. Drops which fall at any angle up to 150 degrees, do not leave marks on the surface.
Formally, the new material is a transparent polymer, but experts say that the developer will use it as glass to create back covers and screen protection.
