The research progress of the stimulus-responsive polymer brushes was summarized in this article. The classification

the way to connect with the substrate and the conventional preparation of the polymer brushes were discussed. The ionic strength-responsive

temperature-responsive

pH-responsive

light-responsive and solvent-responsive polymer brushes and their current research progress were introduced in details

and the corresponding stimulus-responsive mechanism was also discussed. The design and preparation procedure of the multiple stimulus-responsive polymer brushes and their multiple stimulus-responsive properties were summarized. The bending behavior of the substrate resulting from polymer bushes responding to the external stimulus was discussed

and the 3D controllable self-assembling behavior by the bending was presented. The future of the stimulus-responsive polymer bushes was also prospected in this article.
