Enhanced Solvent Exfoliation of Graphite to Graphene Dispersion in the Presence of Polymer Additive

Abstract Enhanced solvent exfoliation of graphite to graphene dispersion is simply accomplished in the presence of various polymer additives. Use of poly(acrylic acid) (PAA) produces exfoliated graphene dispersion up to concentration of 13 µg mL−1, which is much higher than the concentration of graphene dispersion without polymer stabilizer.
