초록

The purpose of this study is to identify the effect of additives during copper electrodeposition. Additives such as arabic gum, chloride ions and glue were used in this study. Electrochemical experiments allied to SEM and roughness examination were performed to characterize of the copper foil in the presence of additives. In the production of electrodeposited copper foil, the surface roughness and grain size of the copper foil can be controlled by addition additives. on this study, the more uniform and hemispherical copper crystals are during the initial stages, the smaller crystal size and surface roughness of copper foil are. The surface roughness of copper foil electrodeposited at the current density of 500 $mA/cm^2$ under galvanostatic mode for 60 seconds has a minimum value of 0.136 ${\mu}$m when adding 2 ppm of arabic gum.
