本文介绍了带相反电荷的聚电解质的交替物理吸附，即所谓的“逐层”方法或“静电自组装”（ESA），用于制备薄的聚合物涂层的最新技术。与其他更成熟的自组织技术相比，这种最新的方法以其简单性，多功能性和速度而闻名。特别是，自我修复的趋势是独一无二的。重点是给出的聚电解质的分子结构的作用，并支持的性质。此外，制备多层膜的各种参数突出显示，这是非常重要的，由于动力学控制的积累过程。讨论了所得涂层的结构、质量和稳定性、膜中的化学反应以及潜在的应用。
The article presents the state-of-the-art of alternating physisorption of oppositely charged polyelectrolytes, the so-called "layer-by-layer" method or "electrostatic self-assembly" (ESA), for the preparation of thin polymer coatings. In comparison to other, more established self-organization techniques, this recent method is distinguished by its simplicity, versatility, and speed. In particular, the tendency for self-healing is unique. Emphasis is given to the role of the molecular structure of the polyelectrolytes, and to the nature of the support. Also, various parameters for the preparation of multilayer films are highlighted, which are very important due to the kinetic control of the build-up process. The structure of the resulting coatings, their quality and stability, chemical reactions in the films, and potential applications are discussed.
