Graphene coatings used to repel, attract water, could make Rain-X decidedly obsolete

Graphene looks poised to replace our silicon and our touchscreens, even fix our batteries. Now it's due for something perhaps a little less revolutionary: keep our pants clean. Physicist James Dickerson and a team of researchers at Vanderbilt University have created two ways to apply thin graphene sheets that either make them super-hydrophobic or super-hydrophilic. These alternate arrangements, termed "rug" and "brick," make the water bead up and run off or spread out and form incredibly thin
