High quality, low oxygen content and biocompatible graphene nanosheets obtained by anodic exfoliation of different graphite types

JM Munuera, JI Paredes, S Villar-Rodil, M Ayán-Varela… - Carbon, 2015 - Elsevier
Anodic exfoliation of graphite has emerged as an attractive method to access graphene
nanosheets in large quantities, but oxidation reactions associated to this process
compromise the structural quality of the resulting materials. Here, we demonstrate that the
type of starting graphite material impacts the oxygen and defect content of anodically
exfoliated graphenes obtained thereof. We investigated highly oriented pyrolytic graphite
(HOPG) as well as graphite foil, flakes and powder as electrode in the anodic process …
