The impedance effect on the ion transport of lithium chloride through temperature‐ and pH‐sensitive gel membranes was investigated. Both conductance and loss tangent show a relatively high value at temperatures near the lower critical solution temperature (14°C), followed by an abrupt drop with a further rise in temperature. The Figure shows an example of changes in absolute complex conductance ( Y ), real conductance ( G ), and imaginary conductance ( B ) for a poly(acryloyl‐ L ‐proline methyl ester) gel membrane.
