While sputtering of metal coatings on polymers is well established, the early deposition stages are still not well understood due to the complex nature of the deposition process. However, particularly the sub-monolayer regime with its transient 2D nanogranular and ramified structures is of great interest for hosts of emerging applications ranging from plasmonics through sensors to organic photovoltaics. These applications require precise control and understanding of the sputter deposition of sub-monolayer metallic nanostructures on polymer surfaces prior to the formation of a closed film. In the current funding period, the early deposition stages were monitored for selected metal-polymer systems in real time with high special and temporal resolution by means of grazing incidence small angle scattering (GISAXS) in a specially designed mobile sputter chamber at the MiNaXS/P03 instrument of the synchrotron radiation source PETRAIII. The unique results, combined with modelling and various other in situ and ex-situ techniques as well as computer simulations have provided a profound understanding of sub-monolayer sputter deposition. In the 2nd funding period, even more complex processes such as deposition of 2D nanogranular metal alloy films and sputtering onto block copolymer films will be studied. For nanoscale metal alloy structures, marked deviations from bulk phase diagrams are to be expected. This will inter alia allow in-situ observation of phase separation in growing complex nanostructures. Block copolymer substrates will give rise to tailored nanostructures, because they involve selective wetting and nucleation on one of the blocks at different tailorable length scales. At a later stage, glancing-angle deposition will provide another exciting subject of investigation.

虽然聚合物上金属涂层的溅射技术已经很成熟，但由于沉积过程的复杂性，早期沉积阶段仍然没有得到很好的了解。然而，特别是具有瞬态二维纳米颗粒和分枝结构的亚单层体系引起了从等离激元到传感器到有机光伏等新兴应用的极大兴趣。这些应用需要在形成封闭薄膜之前精确控制和理解聚合物表面上的亚单层金属纳米结构的溅射沉积。在当前资助期间，通过同步辐射源 PETRAIII 的 MiNaXS/P03 仪器上专门设计的移动溅射室中的掠入射小角散射 (GISAXS)，以高特殊和时间分辨率实时监测选定金属聚合物系统的早期沉积阶段。独特的结果与建模和各种其他原位和非原位技术以及计算机模拟相结合，提供了对亚单层溅射沉积的深刻理解。在第二期资助期间，将研究更复杂的工艺，例如二维纳米颗粒金属合金薄膜的沉积和嵌段共聚物薄膜的溅射。对于纳米级金属合金结构，预计与体相图会有明显偏差。这尤其允许对生长的复杂纳米结构中的相分离进行原位观察。嵌段共聚物基材将产生定制的纳米结构，因为它们涉及不同可定制长度尺度的嵌段之一的选择性润湿和成核。在稍后阶段，掠射角沉积将提供另一个令人兴奋的研究课题。
