摘要

层层组装是一种基于物质交替沉积而制备复合膜的方法

可以实现膜的结构和组成的精确调控.聚合物复合物是基于各种分子间弱相互作用力而形成的超分子聚集体

其种类包括聚阳离子-聚阴离子复合物、聚电解质-有机小分子复合物、中性聚合物-聚合物复合物以及聚合物-无机杂化复合物等.在本文中

以作者的研究结果为基础

阐明聚合物复合物的层层组装是一种方便、快捷的功能复合膜的构筑方法

具有如下优点:(1)聚合物复合物大的尺度可以实现聚合物复合物层层组装膜的快速构筑;(2)聚合物复合物的结构在组装溶液中和成膜后都容易调控

方便聚合物复合物层层组装膜结构的精细调控.(3)聚合物复合物层层组装膜可以构筑非复合的聚合物层层组装所不能获得的膜结构及功能.

Abstract

The layer-by-layer (LbL) assembly has been demonstrated to be a convenient and versatile method to fabricate composite film materials with precise control of film composition and structure.Polymeric complexes represent a large variety of supramolecular assemblies hold together by multiple weak interactions

which include polyelectrolyte-polyelectrolyte complexes

polyelectrolyte-surfactant complexes

non-charged polymer-polymer complexes

polymeric-inorganic hybrid complexes and so forth.We demonstrate herein that the LbL assembly is unique to fabricate functional films by using polymeric complexes as building blocks:(1) It enables rapid fabrication of micrometer-thick films because of the large dimension of the polymeric complexes.(2) It facilitates the flexible control of film structures because the structure of polymeric complexes can be easily tailored in solution or in LbL assembled films.(3) The LbL assembly of polymeric complexes can build up novel functional films which are difficult or impossible to fabricate by LbL assembly of uncomplexed polymers.
