title: The supramolecular structure of ultrafiltration membranes synthesized by electropolymerization.
abstract: The structure and morphology of polyacrylamide-formaldehyde ultrafiltration membranes synthesized by electropolymerization of monomers have been investigated by scanning electron microscopy and scanning tunneling microscopy. The conclusion is that the polymeric film consists of crystalline and amorphous phases. Spherulites occur throughout the entire thickness of the membrane matrix and make the whole structure rigid. The amorphous phase is penetrated by pores directed perpendicularly to the membrane surface. The membranes have an anisotropic sandwich structure with the selective layer formed on the side of the polymer film facing the electrode.
