纳米粒子在聚合物纳米复合膜中的分散性决定了这些体系作为具有独特物理性能的新型材料的应用潜力。将聚合物接枝到纳米颗粒上，主要是无机的，已经被认为是一种有效的策略来增强分散性，从而提高材料的效率。在这篇综述中，我们讨论了控制聚合物接枝纳米粒子在聚合物纳米复合膜中分散的各种参数。我们讨论了表面X射线散射和显微技术如何在聚合物纳米复合薄膜中提供补充和独特的信息，以揭示限制作用下的熵和表面相互作用的微妙相互作用，从而导致纳米粒子在这些薄膜中的分散增强。
Dispersion of nanoparticles in polymer nanocomposite films determines the application potential of these systems as novel materials with unique physical properties. Grafting polymers to, mostly inorganic, nanoparticles has been suggested as an effective strategy to enhance dispersion and hence the efficacy of materials. In this review, we discuss the various parameters which control dispersion of polymer grafted nanoparticles in polymer nanocomposite films. We discuss how surface x-ray scattering and microscopy can provide complementary and unique information in thin polymer nanocomposite films to unravel the subtle interplay of entropic and surface interactions, mediated by confinement, that leads to enhanced dispersion of the nanoparticles in these films.
