Abstract: This outlook paper focuses on micelles formed by introducing more than one kind of polymer blocks with different properties into the same micelle. It can be a plausible candidate that is capable of tuning the resulting properties and meeting various requirements for specific applications. Many parameters may anticipate to affect the formation of stable mixed micelles. Several typical forming types and structures are discussed. There are micelles with different internal structure such as micelles with a heterogeneous core and a homogeneous corona or micelles with a homogeneous core and a mixed corona or core-shell-corona micelles. They possess characteristic stability，drug delivery and stimuli-responsibility. Finally，potential applications of these objects are discussed. Composite structures are expected to realize synergistic drug loading，channel release and drug controlled release. It will play a more important role in the field of drug controlled release.

Key words: complex micelles, comicellization, mixed micelles
