摘要: 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.

摘要: An electrochromic device is disclosed, including two electrochromic elements, which are switched in a time separated manner. Each electrochromic element is arranged of electrochemically active material, and connected to a counter layer by a solidified electrolyte. In at least one embodiment, the electrochromic device further includes at least one resistive device which restricts the electrochemical reaction of one of the electrochromic element, such that a color of this electrochromic element is not substantially altered until the other electrochromic element is reacted to a predetermined extent.

摘要: An electrochemically active element is provided which comprises a first layer of PEDOT-PSS mixed with an adhesion promoter, and a second layer of PANI which is in direct electrical contact with said first layer. Such an element exhibits a substantially increased resistance from being overoxidized, as well as an electrical conductivity which is virtually the same as for pure PEDOT-PSS, and substantially better than for pure PANI. The electrochemically active element can be used in e.g. electrochemical pixel devices, transistors, diodes etc.
