In recent years

hyperbranched polymers has drawn considerable attention in the chemistry

physics

materials

biology

and biomedicine fields for their unique properties not shared with conventional linear polymers

which can be attributed to their highly branched structures. Hyperbranched Polyimide (HBPI) is a new type of polymers based on hyperbranched macromolecules and polyimides

which has the specific three-dimensional molecular structure

highly branched molecular chains and many end-group functional groups on the surface of the molecular. Owing to these unique structural characters

excellent physical and chemical properties

and variety in synthesis and modification

HBPI has gave rise to their potential application in many fields. The application development of HBPI from 1999 when HBPI was first prepared until now in gas permeation membranes

proton exchange membranes

photosensitive and optical waveguide materials

fluorescence

dielectric materials

and composites is reviewed in this paper. The application mechanism in every field mentioned above is summarized

and the forecast to the future developments of the application of HBPI is also discussed.
