Researchers at Purdue University are developing a new graphene "nanopetals" mass production process based on a roll-to-roll process. Those nanopetals are graphene-based vertical nanostructures that look like tiny rose petals, and they have applications in sensors, heat-management, supercapacitors and batteries. This research is funded with a $1.5 million grant from the NSF, and aims to increase the production speed of nanopetal-coated surfaces to 10 square meters per hour (a dramatic increase to current "laboratory-scale" production rate):
