摘要：
The surface properties of pore walls in polycarbonate track-etched (PCTE) membranes was modified by formation of self-assembled monolayers (SAMs) from ω-substituted thiols onto electroless gold deposited on the pore walls of the membrane. SAMs formed from a carboxylic acid-functionalized thiol impart to the membrane high pH-dependence of ionic fluxes across the membrane. The surface-modification procedure described may provide an alternative route to prepare porous ion-selective membranes.
