We demonstrate glancing-angle deposition of gold on a nanostructured diblock copolymer, namely polystyrene-block-poly(methyl methacrylate) thin film. Exploiting the selective wetting of gold on the polystyrene block, we are able to fabricate directional hierarchical structures. We prove the asymmetric growth of the gold nanoparticles and are able to extract the different growth laws by in situ scattering methods. The optical anisotropy of these hierarchical hybrid materials is further probed by angular resolved spectroscopic methods. This approach enables us to tailor functional hierarchical layers in nanodevices, such as nanoantennae arrays, organic photovoltaics, and sensor electronics.
我们展示了在纳米结构的二嵌段共聚物（即聚苯乙烯-嵌段-聚甲基丙烯酸甲酯薄膜）上进行金的掠角沉积。利用金在聚苯乙烯嵌段上的选择性润湿性，我们能够制造出定向的分级结构。我们证明了金纳米颗粒的不对称生长，并能够通过原位散射方法提取不同的生长规律。通过角分辨光谱方法进一步探测了这些分级混合材料的光学各向异性。这种方法使我们能够在纳米器件中定制功能性分级层，如纳米天线阵列、有机光伏器件和传感器电子器件。
