Abstract
The electrical conduction of electrolyte solutions in cyclohexane has been studied between metal electrodes coated with thin films of alumina or polyphenyleneoxide. The ionic injection observed at short times after the application of a voltage step presents the same characteristics as the one previously studied between metallic electrodes (same field dependence, same variation with the liquid conductivity). We conclude that the injected ions are the ions of the electrolyte and are created in the region of image-force in the liquid. After a long application of the voltage, the coating which has blocked the ions of the electrolyte, behaves as a strong injector of ions in the liquid. Revue Phys.
