在简要概述非常规交替层状组装这一进展后,重点总结了如何利用非常规交替层状组装以实现表面印迹膜的制备.模板分子与聚电解质在溶液中组装形成超分子复合物,然后以此超分子复合物为构筑基元,与感光性高分子,如重氮树脂,通过常规交替层状组装形成聚合物多层膜.利用聚合物多层膜之间的光化学反应形成稳定的多层膜,然后去除模板分子得到分子印迹交替组装薄膜.该研究表明不同的分子间相互作用均可用于分子印迹交替组装薄膜的制备,并且通过引入多点相互作用可以提高其选择性.以此为基础,交替层状组装分子印迹薄膜分别与微接触印刷和膜分离技术相结合,制备了具有正电荷选择性的印章材料和电荷选择性的膜分离材料,从而提供一种新的制备表面分子印迹材料的方法.
After briefly reviewing the progress of unconventional alternating layered assembly, it is emphatically summarized how to fabricate the surface imprinted membrane by using unconventional alternating layered assembly.The template molecules and polyelectrolytes assemble in solution to form supramolecular complexes, This supramolecular complex is a building block that is assembled by conventional alternating layered assembly with a photosensitive polymer such as diazo resin to form a stable multi-layer film using photochemical reactions between the polymer multilayer films Membrane, and then removing the template molecules to obtain molecularly imprinted alternating assembly films. This study shows that different intermolecular interactions can be used for the alternate assembly of molecularly imprinted thin films, and the selectivity can be enhanced by the introduction of multi-point interactions. , The alternately laminated molecularly imprinted thin films are respectively combined with the micro-contact printing and the membrane separation technologies to prepare a positive-charge selective seal material and a charge-selective membrane separation material, so as to provide a novel method for preparing the surface molecularly imprinted material Methods.
