The sequential infiltration synthesis (SIS) of inorganic materials in nanostructured block copolymer templates has rapidly progressed in the last few years to develop functional nanomaterials with controllable properties. To assist this rapid evolution, expanding the capabilities of nondestructive methods for quantitative characterization of the materials properties is required. In this paper, we characterize the SIS process on three model polymers with different infiltration profiles through quantification by reference-free grazing incidence X-ray fluorescence. More qualitative depth distribution results were validated by means of X-ray photoelectron spectroscopy and scanning transmission electron microscopy combined with energy-dispersive X-ray spectroscopy.
在过去几年中，纳米结构嵌段共聚物模板中无机材料的顺序浸润合成（SIS）迅速发展，以开发具有可控性质的功能纳米材料。为了助力这一快速发展，需要扩展用于材料性质定量表征的无损方法的能力。在本文中，我们通过无参比掠入射X射线荧光定量分析，对具有不同浸润分布的三种模型聚合物上的SIS过程进行了表征。通过X射线光电子能谱以及扫描透射电子显微镜与能量色散X射线光谱联用，验证了更多定性深度分布结果。
