Summary: | To investigate the effects of mass concentration of thiourea(TU) on the surface morphology, structure and properties of copper foil, as well as the electrochemical behavior of the electrolyte, phosphor copper plate was used as the anode, thiourea(TU), hydroxyethyl cellulose(HEC), polyethylene glycol(PEG-1000) and sodium polydithiodipropane sulfonate(SPS) were employed as combined additives. The electrolytic copper foil was fabricated on a TAl titanium roller using a homemade rotary electroplating device with direct current deposition method. The influence of TU as part of the combined additives on the surface morphology and physical properties of the copper foil was examined using scanning electron microscopy, copper foil tensile strength tester and electrochemical analysis methods. Results showed that within the combined additive system, TU exhibited strong polarization effect, which inhibited the growth of copper nuclei, leading to finer copper foil crystallization. This effect not only enhanced the brightn |
