Systematic and reproducible control over average interparticle spacing of Pt, Ni, and Cu nanoparticles embedded in polyimide thin layers was achieved. The metal-catalyzed decomposition of polyimide matrixes surrounding metal nanoparticles causes a decrease in the composite layer thickness, while maintaining the size of nanoparticles. This ability provides an effective methodology for the preparation of metal/polymer nanocomposites with tailored microstructures and holds great promise toward the fundamental understanding of the physical interactions among metal nanoparticles.
实现了对嵌入聚酰亚胺薄层中的铂、镍和铜纳米颗粒平均粒子间间距的系统且可重复的控制。围绕金属纳米颗粒的聚酰亚胺基体的金属催化分解导致复合层厚度减小，同时保持纳米颗粒的尺寸。这种能力为制备具有定制微观结构的金属/聚合物纳米复合材料提供了一种有效的方法，并对深入理解金属纳米颗粒之间的物理相互作用具有巨大的潜力。
