Study on the electrochromic properties of polypyrrole layers doped with different dye molecules

Three dye molecules (Dye) of Acid Brilliant Scarlet 3R (AR18), Amido Naphthol Red G (AR1), Indigo Carmine (IC), as well as sodium dodecyl sulfate (SDS) as dopant agents were used for electrochemical synthesis of polypyrrole (PPy) layers onto indium doped tin oxide (ITO) coated polyethylene terephtha...

Spectroelectrochemical properties of the films showed that the simultaneous use of each dye molecule and the surfactant as dopant in PPy layers demonstrated proper electrochemical and optical stability and satisfactory electrochromic parameters.

Also, the cathodic and anodic coloration efficiency showed a 6-fold increase in PPy/Dye-SDS compared to PPy/ClO4-. In general, according to the results it is likely that by increasing the number of anion groups in the dye molecules and decreasing their dimensions as dopant agents, the electrochemical and electrochromic properties of the resultant layer would be improved.Peer Reviewed20212021-04-0120212021-10-07journal articlehttp://purl.org/coar/resource_type/c_6501AMhttp://purl.org/coar/version/c_ab4af688f83e57aainfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/2117/353316https://dx.doi.org/10.1016/j.jelechem.2021.115113reponame:UPCommons.
