Crumpled Graphene Resists Aggregation
Graphene flakes can be crumpled into balls that resist compression and aggregation, according to work published in ACS Nano by a Northwestern University-led research team (DOI: 10.1021/nn203115u). In principle, graphene and other sheetlike materials are endowed with high surface area, making them attractive for energy storage and other applications. In practice, however, the thin films tend to aggregate in solution and restack in the solid state, . . .
