Electropolishing characteristics of melamine-functionalized GNP electrode materials |
| 초록 |
Electropolishing is a metal polishing technique mainly used for passivation and deburring of metal products. Currently, copper is the most widely used cathode material and is eluted by electrolyte and oxygen during the electropolishing process, which causes serious water pollution and reduced efficiency. Electrodes fabricated with graphene nanoplatelets (GNPs) have sufficient electrical conductivity for electropolishing and minimize water pollution. Sufficient dispersibility and moldability were obtained by non-covalent functionalization of GNPs using melamine with amine groups. Electropolishing of stainless steel 304 (SS304) was carried out with a copper electrode and a melamine-GNP electrode. The elemental composition of the surface material of SS304 was evaluated by Auger analysis. The surfaces of electrodes before and after electropolishing were observed by SEM. To compare the elution amount, electropolishing was repeatedly performed with each electrode. |
