Abstract

The surface and bulk morphology of a profiled sulfocation-exchange membrane is investigated before and after contact with aromatic amino acid phenylalanine via scanning electron microscopy. It is established that the influence of phenylalanine provokes compaction of the membrane structure due to a decrease in water content and surface hydrophobization. The decreased number and dimensions of macropores on the membrane surface and in its bulk is related to the formation of rather stable spatial associates of phenylalanine.
