摘要：
In the present communication we report on the electrochemical synthesis of highly ordered macroporous copper films in the ionic liquid 1-butyl-3-methylimidazolium dicyanamide [BMIm]DCA using polystyrene (PS) templates. The polystyrene colloidal spheres are arranged onto gold and indium tin oxide substrates in an ordered hexagonal structure. The interstitial voids of the PS sphere arrays are subsequently filled with copper by electrodeposition. After chemical dissolution of the PS spheres well ordered macroporous copper films were obtained. Depending on the experimental parameters, highly ordered 2- and 3-dimensional macroporous Cu films with interconnected pore structure can be made. The macroporous Cu films showed diffractive colours by varying the angle of the incident light. (C) 2012 Elsevier B.V. All rights reserved.
