In this review, recent developments in the fabrication of hexagonal and parallel ordered arrays of metallic nanodomains on a substrate are described. We focus on the nanopatterning approach by means of switchable block copolymer thin films. This approach is highly advantageous, because it can lead to extremely regular patterns with metal subunits of only a few nanometers in diameter and center-to-center distances of tens of nanometers. Hence, the resulting 1D or 2D periodic arrays of metal nanodots and nanowires on silicon substrates can be fabricated with extremely high unit densities and on very large areas. The templated deposition of presynthesized metal nanoparticles on functional block copolymers is described in detail. Current challenges are discussed and an outlook for further developments is given.
在本综述中，描述了在基底上制备金属纳米域六边形和平行有序阵列的最新进展。我们重点关注通过可切换嵌段共聚物薄膜的纳米图案化方法。这种方法具有很大优势，因为它可以产生极其规则的图案，其金属亚基直径仅为几纳米，中心距为几十纳米。因此，可以在硅基底上以极高的单位密度和非常大的面积制备所得的一维或二维金属纳米点和纳米线周期性阵列。详细描述了预合成金属纳米颗粒在功能嵌段共聚物上的模板沉积。讨论了当前面临的挑战，并对进一步发展进行了展望。
