The liquid-phase exfoliation of graphite is mass-producible and cost-effective method of graphene production. Polymers can be employed as dispersants to facilitate the exfoliation of graphite in organic solvents. We synthesized methacrylate polymers with various monomer ratios and molecular weights and investigated the efficient acquisition of graphene from graphite. Graphene with a uniform thickness was obtained when graphite was exfoliated using an optimized polymer dispersant.
