Abstract

Electrostatic exfoliation of patterned few-layer-graphenes was demonstrated using a method compatible with high throughput roll-to-roll manufacturing. A patterned graphite template was placed on a roller and used to exfoliate patterned graphene on a planar substrate. The exfoliated graphene features were subsequently characterized by Raman spectroscopy. In comparison with previously demonstrated planar electrostatic exfoliation approach, the roller-style method can create a narrower distribution of thickness of few-layer-graphenes, which is attributed to the combinational action of tangential rolling friction and electrostatic forces. This roller-style electrostatic printing technique could be applied for roll-to-roll manufacturing of graphene-based devices in the future.
