摘要：

Three-dimensional bimodal porous Cu comprises oriented Gasar pores and random dealloyed pores was prepared by chemically dealloying Gasar Cu-34.6 wt% Mn alloy. The influence of dealloying parameters on slice samples was investigated, and a typical structure was fabricated in 10 vol% HCl at 90 degrees C for 12 h of dealloying. The dealloyed morphology on the fracture was identical to that on the surface, with regularly arranged sub-micrometer strips and assembled nanometer pores. Cuboid (8 mm x 8 mm x 10 mm) and column (Phi 8 mm x 20 mm) samples of bulk three-dimensional bimodal porous Cu were obtained after dealloying in 10 vol% HCl for 72 h. (C) 2013 Elsevier B.V.
