摘　　要：概述了作者及其研究群体发展的基于氢键、配位键和共价键的聚合物交替沉积组装方法.在此基础上,重点讨论将溶液中的超分子组装与界面交替沉积相结合的非常规界面交替沉积组装方法.通过结构构筑与功能组装的结合,实现了不同表面物理化学性质的可控调节,包括仿生矿化、超疏水涂层、可控组装与释放、表面分子印迹等.这些研究结果对发展基于聚合物多层膜的表面分子工程具有重要意义.This feature article has summarized our research on basis of hydrogen bonding, coordination bonding and covalent layer-by-layer deposition films of polymers on the bonding. Moreover, our discussion has focused on unconventional methods of layer-by-layer deposition that invovles supramolecular assembly in solution and layer-bylayer deposition at solid/liquid interface. It has been demonstrated how to combine structural architectures with functional assembly leading to controlling the physicochemical properties of the surfaces, including biomineralization, superhydrophobic coating, controlled assembly and release, and surface molecular imprinting. It is anticipated that this line of research is of significance for developing surface molecular engineering of polymer muhilayer films.
