However, the ageing of such a device must be investigated before any application. Therefore, our investigations focus on the ageing of the components of a polycarbonate based electrochromic device. The optical, electrical, mechanical and electrochemical properties of the ion storage layer as well as the substrate will be assessed after storage in a climate with a high humidity and high temperature level.

A review of organic electrochromic fabric devices / Whitney M. Kline in COLORATION TECHNOLOGY, Vol. 130, N° 2 (04/2014)  

[article]  inCOLORATION TECHNOLOGY > Vol. 130, N° 2 (04/2014) . - p. 73-80 Titre : A review of organic electrochromic fabric devices Type de document : texte imprimé Auteurs : Whitney M. Kline, Auteur ; Robert G. Lorenzini, Auteur ; Gregory A. Sotzing, Auteur Année de publication : 2014 Article en page(s) : p. 73-80 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Conducteurs organiques Dispositifs électrochromiques Polymères électrochromes Textiles et tissus Index. décimale : 667.3 Teinture et impression des tissus Résumé : Electrochromic fabric devices represent a further extension to the plethora of available literature on conductive fabrics. This article contains a brief overview of electrochromic devices, electrochromic polymers, conductive materials, conductive fabrics, and electrochromic fabric devices. A tabulated list of the perceived colour of a number of electrochromic polymers that is contained herein is designed to serve as an aide to colour mixing studies. The challenges of optimisation and commercialisation of electrochromic fabric devices and their mitigating factors are conjectured, along with some future potential applications for electrochromic fabric device technologies.

The effects of coloured base fabric on electrochromic textile / Michael A. Invernale in COLORATION TECHNOLOGY, Vol. 127, N° 3 (2011)  

[article]  inCOLORATION TECHNOLOGY > Vol. 127, N° 3 (2011) . - p. 167-172 Titre : The effects of coloured base fabric on electrochromic textile Type de document : texte imprimé Auteurs : Michael A. Invernale, Auteur ; Yujie Ding, Auteur ; Gregory A. Sotzing, Auteur Année de publication : 2011 Article en page(s) : p. 167-172 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Dispositifs électrochromiques Polymères électrochromes Teinture -- Fibres textiles Index. décimale : 667.3 Teinture et impression des tissus Résumé : The colour of electrochromic fabric, and its colour transitions, was explored on the basis of variations in underlying fabric colour. A complete understanding of this phenomenon is essential for the fabric’s use in full-colour wearable displays or other applications. Previous work in this area utilised only white-coloured starting materials. Herein, a large colour swathe of fabrics was chosen. They were loaded with the commercially available conducting polymer, PEDOT-PSS, and were coated with an electrochromic polymer. These all-organic substrates were then switched between their two coloured states via reversible oxidation and reduction. At every stage, coordinates in the CIE Lu′v′ colour space were measured. It was found that darker colours decrease the overall contrast of the electrochromic, with black being entirely unobservable. More vibrant colours affected the observed colour through a subtractive mixing effect, as expected, but no adverse contrast effects between the two states of the electrochromic system was observed.
