Ni nanoparticles embedded in a polyimide (PI) matrix were fabricated by selectively oxidizing a layer of Ni(80)Fe(20) metal film sandwiched between two PI precursor layers. Ni nanoparticles, formed in a monolayer between two PI layers, had an average particle size of approximately 5 nm. X-Ray photoelectron spectroscopy confirmed that Fe in the film was preferentially consumed, resulting in the formation of Ni nanoparticles.
通过选择性氧化夹在两个聚酰亚胺（PI）前体层之间的一层Ni(80)Fe(20)金属膜，制备了嵌入聚酰亚胺（PI）基质中的镍纳米颗粒。在两个PI层之间的单层中形成的镍纳米颗粒的平均粒径约为5nm。X射线光电子能谱证实，薄膜中的铁被优先消耗，从而形成了镍纳米颗粒。
