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.
