Abstract:
1. An electrochromic module comprising a first substrate, a second substrate, the first and/or second substrate being either electrically conductive or having been provided with an electrically conductive coating, a coating of an electrochromic polymer disposed on the substrate or the conductive coating, an ion storage layer disposed on the substrate or the conductive coating and an electrically series-connected electrolyte disposed between the electrochromic coating and the ion storage layer, wherein the electrochromic polymer is an essentially linear condensation polymer which has been formed from a tetraarylbenzidine and a (hetero)aromatic diol and can be switched reversibly under voltage control between more than two redox states, the condensation polymer being colorless in one redox state and colored in at least two redox states, and the electrolyte is a polymeric gel electrolyte.
