采用化学腐蚀法在Gasar孔的内表面制备了具有规则的Gasar微米或毫米孔和随机脱合金纳米孔的双峰多孔铜。为了实现这一目标，进行了两步腐蚀方法，包括选择性腐蚀的Zn元素从Cu-Zn合金层的NaOH溶液，和在第一步中获得的表面氧化物的去除暴露底部的纳米多孔铜膜的HCl溶液。讨论了HCl溶液浓度、处理时间、NaOH溶液脱合金时间、Gasar孔直径、Gasar孔开口距离等制备条件对纳米多孔Cu薄膜微观结构的影响。
A bimodal porous Cu with regular Gasar micrometer or millimeter pores and random dealloying nanometer pores was fabricated by chemical corrosion of Cu–Zn alloy layers on the inner surface of Gasar Cu pores. In order to accomplish this object, a two-step corrosion method was conducted, including the selective corrosion of Zn element from Cu–Zn alloy layers by NaOH solution, and the removal of the surface oxide obtained in the first step to expose the bottom nanoporous Cu films by HCl solution. Influences of preparation conditions, such as HCl solution concentration and processing time, NaOH solution dealloying time, Gasar pore diameter, and the distance from Gasar pore openings on the microstructure of the resulting nanoporous Cu films were discussed.
