Abstract
A process for rendering an electrically conducting polymer essentially non-conducting is provided, in which the polymer is brought into direct electrical contact with an electrolyte. Furthermore, an electric voltage is applied to the polymer using at least two electrodes connected to a voltage supply, each electrode independently being in electrical contact with one of the polymer and the electrolyte. The electrically conducting polymer is rendered non-conducting through electrochemical reactions occurring in the interface between the polymer and the electrolyte in response to the electric voltage.
