Polymeric dispersants for graphenes
Kyungpook National University Industry-Academic Cooperation Foundation, Daegu, Korea
We developed amphiphilic block copolymers for exfoliation of highly ordered pyrolytic graphites and their dispersions. This technique provides better dispersion stability through non-covalent modification of graphene minimizing defects. Unlike graphene oxides or reduced graphene oxides, exfoliated pyrolytic graphites (i.e. graphene) show better barrier and electrical properties due to the minial defects.
