Effect of Additives in an Electrolyte on Mechanical Properties of Electrolytic Copper Foil
説明
<jats:p>The effect of additives in electrolyte on mechanical properties of electrolytic copper foil was investigated. Bis-(3-sulfopropyl)-disulfide disodium salt (SPS), animal protein of low molecular (PBF) and hydroxyethyl cellulose (HEC) were added in electrolyte as additives. The additive amount of SPS was changed in this study. The addition of SPS is effective to improve tensile strength and hardness of electrolytic copper foil. With increasing the additive amount of SPS, the grain of electrolytic copper became finer and thus its hardness and elastic modulus increased. On the other hand, fatigue properties improved when the additive amount of SPS decreased and the grain size of electrolytic copper became relative large.</jats:p>
