Self-assembled nanostructure is a prevalent phrase in chemistry in recent years. Block copolymers in a selective solvent can be self-assembled to micelles. Polymer micelles may eventually prove to have important technological applications. We have studied interpolymer complexation through specific interactions for years. However, the complexation usually does not lead to well-defined structures. Our new approach is: when polymer A is dissolved in a good solvent and added to a solution containing polymer B in a nonsolvent for A, the precipitation of A can be prevented due to the specific interaction between A and B, and instead, micelles with A core and B corona are formed. Similarly, it is also possible to prepare "graft copolymer" between A and B in a common solvent via hydrogen bonding first, then mix it with a selective solvent to form A-B micelles. This kind of micelle differs from the conventional block copolymer micelles, in which the corona and the core are chemically bonded. This paper summarizes our major recent results on this new approach to several different kinds of systems, either in organic or in aqueous media.
