Dispersion of Graphene Sheets in Organic Solvent Supported by Ionic Interactions

Authors


Abstract

Organic solution-processable graphene sheets were prepared using a large-scale novel approach based on a transfer process assisted by ionic interactions. Smooth monolayer graphene sheets were easily fabricated on a substrate from organic solution. Such a noncovalent functionalization preserves the extended aromatic conjugation of reduced graphene sheets, giving rise to high-conductivity cast films.
