摘要：
Polymer chains extend and contract in response to the changes of environmental conditions in solution. In the present article, several signal-responsive polymers were grafted on porous membranes as brushes, and the permeation control by the extension and contraction of the graft chains on the porous membrane surface was summarized. First, the permeation control mechanism and the characteristics of such membranes were described. Secondly, the permeation controls in response to pH, temperature, photo-irradiation, redox reaction, and glucose concentration were discussed. Finally, some grafting methods to construct signal-responsive porous membranes were mentioned.
