In the past two decades, layer-by-layer (LbL) assembly has been proven to be a convenient and versatile method to fabricate functional films. However, using traditional dipping LbL assembly to fabricate micrometer-thick films is time consuming. Compared with ultrathin films, micrometer-thick films prepared by LbL assembly possess enhanced mechanical stability, and allow deposition of a significantly increased amount of materials and the integration of multiple functions. These merits of thick films produced by LbL assembly can result in new functions and allow the functions of ultrathin films fabricated by LbL assembly to be optimized. In this tutorial review, the methods for rapid fabrication of thick polymeric films involving LbL assembly are reviewed. The functions of such films that are relevant to their micrometer thickness are discussed.
在过去的二十年中，层层组装（LbL）已被证明是一种方便且通用的方法来制备功能性薄膜。然而，使用传统的浸渍 LbL 组装来制备微米级厚的薄膜是耗时的。与超薄薄膜相比，LbL 组装制备的微米级厚薄膜具有增强的机械稳定性，并且允许沉积大量的材料和集成多种功能。LbL 组装制备的厚膜的这些优点可以产生新的功能，并允许优化通过 LbL 组装制备的超薄薄膜的功能。在本综述中，综述了涉及 LbL 组装的快速制备厚聚合物薄膜的方法。讨论了与这种薄膜的微米厚度相关的功能。
