Resumo |
Graphene was produced by electrochemical exfoliation of a used battery electrode. Aqueous solutions of cationic (cetyltrimethylammonium bromide), anionic (sodium dodecyl sulphate), and nonionic (poly vinyl pyrrolidone) surfactants, along with NaCl and combinations of these surfactants with NaCl, were used as the electrolyte. The following observations were made: (I) up to several micrometer sized graphene sheets were produced, (II) the addition of NaCl into the electrolytes significantly enhanced the yield of the exfoliated graphene, (III) the type of surfactant affected the defect density of the exfoliated product, and (IV) electrochemical impedance spectroscopy provided insight into the reason for the changes in the defect density ratio between the graphene samples. |
