: The materials that change color on passing a charge are called electrochromes. A wide range of both inorganic and organic chemicals exhibit electrochromism. Among these materials electroactive conducting polymers have offer advantages, such as outstanding coloration efficiency, fast switchingability and multiple colors from the same electrochromic system. The properties of conducting polymers are strongly dependent on the dopant types used. In the present research, the electrochromic film made of doped polymer was produced and its color change by applied voltage was investigated. For this purpose, the electropolymerization of a pyrrole monomer was done using three dye molecules, acid red 18 (AR18), acid red 1 (AR1) and indigo carmine (IC), alone or in combination with sodium dodecyl sulfate (SDS). The prepared polypyrrole (PPy) showed higher redox capacity when SDS and dye molecules were used simultaneously as dopant agents than when the conducting polymer was produced in the presence of SDS, AR18, AR1 or IC. Moreover, the prepared PPy/Dye-SDS electrochromic system is a self-stabilizing material that exhibits increasing electrochemical activity with increasing the number of oxidation–reduction cycles. In this system all the three dye molecules have self-stabilizing effect, however, this effect was more significant in the presence of AR18.This higher effect is likely to be due to the higher surface charge distribution and smaller dimensions of the AR18. A mechanism supported by scanning electron microscopy and X-ray diffraction structural observations was proposed to explain the synergy between the SDS and the dye molecules. AFM analysis of doped PPy films showed the presence of the dye molecule reduces the surface roughness of the PPy films and the roughness it was observed that the surface roughness reduces with increasing the linearity of the dye molecule structures. The presence of the dye molecules in the PPy chains was confirmed by XRD analysis. In addition, the UV-Vis-NIR absorption spectra of the films confirmed the formation of polaron and bipolaron chains in the PPy. The calculation of the optical band gap in the PPy/Dye-SDS films also showed a reduction of 59% optical band gap and PPy was fully doped. Spectroelectrochemical study on electrochromic films showed satisfactory behaviors electrochromic parameters. The spectroelectrochemical study showed improvement in the electrochromic parameters of the films and satisfactory electrochromic behaviors, such as 55% increase in optical contrast and a high increase in coloration efficiency. Electrochemical and electrochromic properties of the films improved by increasing surface charge distribution and decreasing dimensions of the dye molecules. Using color calculations on the absorption spectra of the films in the -1V and +1V potential range, the color coordinates of PPy/Dopants films in the CIELAB color space, CIExyY color space and RGB of display color space were obtained. The results showed that the dopant type affects the behavior of color changes on the final electrochromic films. Also, the presence of the dye molecule not only changes but also widens the color gamut of the doped PPy films. In addition, the CIELAB color differences between different electrochromic films were between 10 to 45, which is considerably high and recognizable.
