The grafted polymers shrank and extended in response to environmental signals, such as pH, ionic strength, temperature, redox reaction and photo-irradiation. The pore size was regulated by the extent of the polymer brush. The phenomenon was observed in situ by atomic force microscopy. As a result, the substance permeation through the porous membrane was controlled in response to the signals. The permeation control was rapid in comparison with hydrogel-type membranes, and was reversibly performed. Copyright (C) 2000 John Wiley & Sons Ltd. English John Wiley & Sons Inc.
