Abstract:Conductive MWNT/ABS composite cathode and matching electrolytic cell were fabricated by 3D printing to substitute normal titanium substrate cathode. Obtained in copper sulfate electrolyte, compact and uniform copper layers of fcc crystal system could be easily peeled off from composite cathode. Structures of cathode and cell are designable. Cyclic voltammetric investigation suggests that nucleation and growth of copper are similar to those on metal cathodes, and additives of gelatin and thiourea can apparently reduce crystal size and make copper deposit uniform and compact.
