尽管脱合金法通常用于制备纳米多孔(NP)金属，前驱体合金成分和脱合金化条件决定了韧带和孔的长度尺度，但该技术通常允许对韧带/孔大小和NP几何形状的设计进行有限的控制。本文提出了一种通过薄膜厚度来制备具有层状结构的NP金属薄膜的新方法。对Au和Ir合金薄膜的实验表明，这种方法可以成功地控制韧带的大小、间距和均匀取向。
Although dealloying is commonly used to fabricate nanoporous (np) metals, with precursor alloy composition and dealloying conditions determining the length scale of ligaments and pores, the technique typically allows limited control over ligament/pore size and design of np geometry. This paper presents a novel approach to creating np metal films with layered structure through the film thickness. This method is demonstrated for Au and Ir alloy films and can successfully control ligament size, spacing, and even orientation.
