International Collaboration: Complexes of Block Ionomers with Oppositely Charged Homopolymers and Surfactants

这项国际合作的目的是研究：(1)由离子性嵌段共聚物和带相反电荷的合成多离子形成的配合物；(2)离子性嵌段共聚物与带相反电荷的表面活性剂形成的配合物。这些配合物代表了一类新的材料，它们结合了协同性聚电解质或聚合物胶体配合物的性质（对离子强度和pH值的敏感性，参与协同性多离子交换和取代反应的能力）和两亲性嵌段共聚物形成胶束和中间相的能力。预计这些材料将在药物传递和释放、膜技术、生物相容性材料和生物催化等各个领域得到应用。＊＊＊

9617837 Kabanov The objective of this international collaboration is to investigate: (1) complexes formed by ionogenic block copolymers and oppositely charged synthetic polyions; and (2) complexes formed by ionogenic block copolymers and surfactants of opposite charge. These complexes represent new classes of materials which combine the properties of cooperative polyelectrolyte or polymer-colloidal complexes (sensitivity to ionic strength and pH, ability to participate in cooperative polyion exchange and substitution reactions) with the ability of amphiphilic block copolymers to form micelles and mesophases. %%% It is expected that these materials could find applications in various fields including drug delivery and release, membrane technologies, biocompatible materials, and biocatalysis. ***
