Abstract
Poly(L-glutamic acid) (PLGA) carrying a terminal disulfide group at one end of the chain was self-assembled on a porous membrane. The rate of water permeation through the surface-modified porous membrane depended on pH. In the region of low pH, the PLGA chain is protonated and folded to form an -helix; in the region of high pH, it is de-protonated to have extended random coil structure. The ionic strength also regulated the rate of water permeation. Increasing ionic strength reduced the pH dependence of permeation due to a shielding effect. The permeation through the porous membrane, the surface of which was covered with the self-assembled polypeptide pelage, was sensitively regulated by changing the pH because of direct contact of pelage chains with the environment.
