Graphene’s Imperfect and Cheaper Form Helps Develop Nanoscrolls

In the future, billions of small graphene-based nanoscrolls could be used to develop water filters. A single, atom-thick layer of graphene is rolled up to make a single scroll. Each scroll can be custom made to trap particular molecules and pollutants in its firmly wound rolls. A highly selective, durable, and lightweight water purification membrane can be developed by stacking billions of these nanoscrolls in layers.
