Steel corrosion inflicts an enormous annual \neconomic damage, which could be reduced by the installation of \nappropriate monitoring devices. These should be simple, reliable, long \nlasting, and should not require service or maintenance. The present \nelectrochromic device is constructed in such a way that it uses the \nmacrocell current in an active, chloride\u2010induced corrosion element as \npower supply to trigger the colour change. This way, the system stays \ninactive until corrosion occurs. The device consists of diheptyl \nviologen in a liquid polymer electrolyte made from LiClO4 and \npoly(ethylene glycol) with Mw = 400 g mol\u22121. The addition of viologen \nlowers the resistance but causes no further changes in the \nelectrochemical properties of the polymer electrolyte. Impedance spectra\n indicate ion transport rather than capacitance effects to dominate the \nelectrochemical properties. Experiments using direct current in the \nmicroampere range show electrochromic switching times of several \nminutes, which is sufficient for the intended monitoring application.<\/p>","protected":false},"excerpt":{"rendered":"<p>T.
