In recent years, metallopolymers have attracted much attention as precursors to generate magnetic metal/metal alloy nanoparticles (NPs) through pyrolysis or photolysis because they offer the advantages of ease of solution processability, atomic level mixing and stoichiometric control over composition. The as-generated NPs usually possess narrow size distributions with precise control of composition and density per unit area. Moreover, patterned NPs can be achieved on various substrates in this way owing to the good film-forming property of metallopolymers and such work is important for many applications based on metal nanostructures. By combining the merits of both the solution processability of metallopolymers and nanoimprint lithography (NIL), a new platform can be created for fabricating bit-patterned media (BPM) and the next-generation of nanoscale ultra-high-density magnetic data storage devices. Furthermore, most of these metallopolymers can be used directly as a negative-tone resist to generate magnetic metallic nanostructures by electron-beam lithography and UV photolithography. Self-assembly and subsequent pyrolysis of metalloblock copolymers can also afford well-patterned magnetic metal or metal alloy NPs in situ with periodicity down to dozens of nanometers. In this review, we highlight the use of metallopolymer precursors for the synthesis of magnetic metal/metal alloy NPs and their nanostructures and the related applications.
近年来，金属聚合物作为通过热解或光解生成磁性金属/金属合金纳米颗粒 (NPs) 的前体引起了广泛关注，因为它们具有易于溶液加工、原子级混合和组成的化学计量控制的优点。所生成的 NPs 通常具有窄的尺寸分布，并能精确控制组成和单位面积的密度。此外，由于金属聚合物具有良好的成膜性能，因此可以在各种衬底上实现图案化的 NPs，这对于基于金属纳米结构的许多应用非常重要。通过结合金属聚合物的溶液加工和纳米压印光刻 (NIL) 的优点，可以为制造位图案介质 (BPM) 和下一代纳米级超高密度磁数据存储设备创建一个新平台。此外，大多数这些金属聚合物可以直接用作负性抗蚀剂，通过电子束光刻和紫外光刻生成磁性金属纳米结构。金属嵌段共聚物的自组装和随后的热解也可以原位提供具有周期性低至数十纳米的图案化磁性金属或金属合金 NPs。在这篇综述中，我们重点介绍了金属聚合物前体在磁性金属/金属合金 NPs 及其纳米结构合成中的应用。
