Caption: This is a 2-D view of a graphene sheet (black) and attached sidegroups (blue) that IU Bloomington chemist Liang-shi Li and his collaborators devised. In reality, each sidegroup rotates 90 degrees or so out of graphene's plane. The three blue, tail-like hydrocarbons of each sidegroup have great freedom of movement, but two are likely to hover over the graphene, making it very unlikely that one graphene sheet will touch another.
