Abstract

Cellulose acetate (CA)-based membranes are used for Mg dissolution

control: the permeability of the membrane is adjusted by additions of the

polyelectrolyte, poly(N,N-dimethylaminoethyl methacrylate) (PDMAEMA). Spincoated

films were characterized with FT-IR, and once exposed to an aqueous solution

the film distends and starts acting as a membrane which controls the flow of ions and

H2 gas. Electrochemical measurements (linear sweep voltammograms, open-circuit

potential, and polarization) show that by altering the CA:PDMAEMA ratio the

dissolution rate of Mg can be controlled. Such a control over Mg dissolution is crucial

if Mg is to be considered as a viable, temporary biomedical implant material.

Furthermore, the accumulation of corrosion products between the membrane and the

sample diminishes the undesirable effects of high local pH and H2 formation which

takes place during the corrosion process.
