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. ***

这项国际合作的目的是研究：（1）由离子型嵌段共聚物和带相反电荷的合成聚离子形成的复合物;和（2）由离子型嵌段共聚物和带相反电荷的表面活性剂形成的复合物。 这些配合物代表了新的材料类别，其将协同的胶束或聚合物-胶体配合物的性质（对离子强度和pH的敏感性，参与协同的聚离子交换和取代反应的能力）与两亲性嵌段共聚物形成胶束和中间相的能力结合联合收割机。 预计这些材料可以在包括药物递送和释放、膜技术、生物相容性材料和生物催化的各个领域中找到应用。 ***
