Effect of Additives on Electrodeposition of Copper in Ch Cl-Gl A Low Eutectic Solvent by LIU Yang, HAO Jianjun, YIN Hongkun, WANG Xinhui

“…The use of additives facilitates the deposition of copper on metal substrates.In this work，using choline chloride glacial acetic acid(Ch Cl-Gl A) as a low eutectic solvent and copper acetate as the main salt， the effects of ascorbic acid(C6H8O6)， disodium ethylenediamine tetraacetic acid(EDTA-2Na) and diethylenetriaminepentaacetic acid(DTPA) as additives on electrodeposition of copper on iron substrate were investigated.Electrochemical behavior was studied by cyclic voltammetry (CV) and chronoamperometry (CA)； scanning electron microscopy(SEM) and X-ray diffraction(XRD) were used to observe and analyze the morphology and composition of the coating.The UV-visible absorption spectrum of the complex formed in the electrodeposited solution with different additives was analyzed by a UV-Vis-NIR spectrophotometer.Results indicated that in Ch Cl-Gl A， the electrodeposition of copper involved two steps of oxidation-reduction with the first step of Cu2＋→Cu＋and the second step of Cu＋→Cu.All three additives promoted the deposition of copper in Ch Cl-Gl A，and ascorbic acid had the best effect，which could obtain a copper coating with good performance at room temperature.The electrodeposition of copper in Ch Cl-Gl A followed a three-dimensional instantaneous nucleation process and was an irreversible reaction controlled by diffusion.Moreover，the diffusion coefficients of Cu2＋and Cu＋could reach 4.003 9&#x00D7;10－7&#x00A0;cm2/s，4.762 7&#x00D7;10－7&#x00A0;cm2/s，respectively.The copper crystal prepared with ascorbic acid as additive was a polygonal sheet-like structure with distinct grains，and the optimal crystal plane was the (111) crystal plane.Besides，the average grain sizes of the copper layer with additives DTPA，EDTA-2Na and C6H8O6&#x00A0;were 50.71，55.12 and 52.73 nm.The average grain size of the copper layer without additive was 44.73 nm.…”
