Northwestern U. Crumples Graphene for Better Sheeting

The avoid graphene stacking, the team’s new material – is made by crumpling the graphene sheets into balls. The approach was inspired by a trash can full of crumpled-up papers, according to researchers. "The balls can stack up into a tight structure. You can crumple them as hard as you want, but their surface area won't be eliminated, unlike face-to-face stacking," said Jiaxing Huang, Morris E. Fine Junior Professor in Materials and Manufacturing.

The work is published as "Compression and Aggregation-resistant Particles of Crumpled Soft Sheets," in October 13 edition of ACS Nano.
