Of concern is the mechanical and dimensional stability as well as the chemical
stability. As noted above, the demands on chemical stability are greatest when
the membrane is adjacent to an electrode; then the membrane may need to be ...

The chemical stability of the membrane polymer to attack by the electrolyte
solutions is obviously crucial. The electrolyte solutions may have an extreme pH
and/or contain strong oxidising or reducing agents. Anion permeable membranes
are ...

Their key advantages are mechanical and dimensional stability even when made
as very thin membranes (down to 5 fxm); chemically, the Gore-SelectTM
materials retain the properties of the ion exchange polymer used. At the present
time, ...
