The effects of cationic polymer additives on gold electrodeposition citric acid baths and the corrosion resistance of gold plating films were investigated by physicochemical methods. In a bath containing a small amount (5ppm) of poly (ethyleneimine) derivative such as ethoxy-modified (PEIEt), film porosity decreased significantly and deposition efficiency decreased slightly. The lower film porosity in the bath with PEIEt is due to the fine structure of grain and the leveling effect of surface. In polymer additives such as PEIEt, the effective property given the lower film porosity and higher deposition efficiency can be obtained by the balance between continuous adsorption ability and steric hindrance of polymer.
