Polymer chains attached onto materials surface by physical adsorption or chemically grafting and formed brush-like polymer monolayer is called as polymer brush. Stimuli-responsive polymer brushes display reversible changes on the physical and chemical properties in accordance with the small external changes in their environment. The polymer chains conformation could stretch or collapse

which has shown great potential application in recent years. The development of stimuli-responsive polymer brushes

including pH-responsive

temperature-responsive

and photo-responsive polymer brushes and different synthesis methods

were reviewed. Their applications in intelligent membrane

drug delivery

catalysis

self assembly

molecular device

and so on were introduced with some emphasis.
