ELECTROCHEMICALLY SYNTHESIZED COPPER NANOTUBES AND NANOROD ARRAYS IN POLYCARBONATE MEMBRANES

The large area, highly uniform copper nanorod arrays with cylindrical morphology in polycarbonate membranes (PC) have been successfully prepared by electrochemical deposition. The copper nanorod arrays have the length of 3 μm, the diameter of 400 nm, approximately, which correspond closely to the pore diameter and thickness of membranes. The copper nanotubes were also obtained by controlling initial voltage and polycarbonate membranes treatment process. The possible growing mechanisms of copper nanostructures in membrane pores were discussed.
