Electrodeposition and characterization of copper nanocone structures

In this work, large-scale Cu nanocone arrays were synthesized by a one-step electrodeposition method without any template. The surface morphologies of Cu deposits prepared under different fabrication conditions have been observed. The as-prepared Cu nanocones grow preferentially along the <111> direction. The formation mechanism of the nanocone structure can be explained by the screw dislocation driven growth theory. In addition, this electrodeposited Cu film with nanocone structure exhibits a superhydrophobic property after chemical modification.
