New coating may lead to fog- and dirt-free windshields
If you're like us and haven't washed your car since, like, ever, you're probably used to the windshield getting all fogged up (not in the good, make out point way, however) and habitually swiping at the glass with your sleeve while swerving between lanes and praying that your airbag still works. Well thanks to a new coating developed by researchers at Purdue University, your dangerous driving habits may soon be a thing of the past (well, except for those occasions when you're texting your buddies while eating a cheeseburger and fiddling with the radio), as this material has the unique ability to both prevent the formation of water droplets (no more fog!) as well as cause oil-based substances to bead up for easy cleaning (no more road grime!). The science behind this breakthrough is a little boring (i.e. we don't really understand it), but it seems that by covalently bonding a DuPont substance known as Zonyl FSN-100 to ordinary glass, the component polymers are able to change shape and react differently depending on the chemicals they come into contact with. After figuring out a way to apply the coating cheaply through spray or roll-on techniques, the next step for the Boilermakers will be to coax the material into repelling other nasty substances, making it suitable for use on the gadgets and glasses we geeks hold so dear.
