Copper Oxalate Multilayer Micro-Sheet Film Grown Directly on Cu Substrate

Abstract

A kind of copper oxalate film was prepared in aqueous acid solution at room temperature. During the preparation, a copper foil was used as substrate while K₂S₂O₈ was used as oxidizing agent. The film prepared was covered with micro-sheets which had polymer-like structure. This technique could be considered as an effective way to energy-retrenched, time-saving and environment friendly.
