胶体界面吸附和接枝的散射技术研究

Adsorption and grafting on colloidal interfaces studied by scattering techniques

Julian Oberdisse

摘要:

聚合物和表面活性剂分子在溶液中的胶体颗粒或液滴上的吸附可以通过散射技术非破坏性地表征。在第一部分中,动态光散射,小角中子和X射线散射的一般框架的吸附层的结构的测定,即密度分布,提出。然后,我们回顾了最近的研究层的模型聚合物聚(环氧乙烷),作为均聚物或嵌段共聚物的一部分。在这一领域,散射与对比度变化已被证明是一个强大的工具,以获得详细的描述的层结构。本文还讨论了化学性质更为复杂的复杂系统,包括聚电解质、聚合物复合物、接枝链和生物大分子的吸附,以及表面活性剂的吸附。

英文摘要:

The adsorption of polymer and surfactant molecules onto colloidal particles or droplets in solution can be characterized non-destructively by scattering techniques. In a first part, the general framework of Dynamic Light Scattering, Small Angle Neutron and X-ray Scattering for the determination of the structure of adsorbed layers, and namely of the density profile, is presented. We then review recent studies of layers of the model polymer poly(ethylene oxide), as homopolymer or part of a block copolymer. In this field, scattering with contrast variation has been shown to be a powerful tool to obtain a detailed description of the layer structure. Adsorption of chemically more complex systems, including polyelectrolytes, polymer complexes, grafted chains and biomacromolecules are also discussed in this review, as well as surfactant adsorption.
