“…Recently, the electrically conducting polymers (CPs) such as polypyrrole, polythiophene and their derivatives were reported in electrochromic device applications because of their fast switching times, high contrast ratio, solution-processability, low power consumption and generation of multicolor [11][12][13][14]. Many researchers have extensively studied the EC properties of poly(3,4-ethylenedioxythiophene) (PEDOT) and its derivatives because of their chemical stability, low oxidation potential, good environmental stability, and ease of processability [15][16][17][18].…”

An electroactive poly(3,4-(2,2-dimethylpropylenedioxy)thiophene) (PProDOT-Me 2 ) thin film was electropolymerized by cyclic voltammetry technique, and its electrochemical and electrochromic properties were systematically studied. The prepared PProDOT-Me 2 thin film was electrochemically reversible, and it showed a linear relation between peak current with scan rates. The electrochemical impedance spectrum also indicated the diffusion limitation of the film during charge/discharge process. The film showed a good color contrast (60 %) with a low applying potential of 1.2 V. The electrochromic window (ECW) based on PPro-DOT-Me 2 film was fabricated and studied for its electrochromic performance. The color contrast of the device was achieved as 36 % at k max of 560 nm. The switching speed of fabricated ECW for coloring and bleaching were almost 0.7 s in a range of ?1.5 to -1.5 V. The fabricated device showed better cyclic current response and remarkable switching stability over 100 cycles. The novelty of the electrochromic window based on PProDOT-Me 2 is the maximum absorbance at photopic wavelength that would be highly sensitive to human eyes.

“…2 Thus, polypyrrole is used in many applications, such as batteries, electronic and electrochromic devices, sensors, super capacitors, functional coatings, microwave absorbing and shielding, and corrosion control. 9 Physical and chemical properties of polypyrrole may vary according to the factors such as the kind of doping anion, electro-polymerization method, selected solvent, and the electrode substrate. 10 The structure and size of the dopant also affect the properties of polypyrrole.…”

Polypyrrole and Al doped polyprrole thin films were synthesized by electrochemical deposition method. FTIR spectroscopic studies confirm the formation of PPy and Al:PPy thin films. From the FESEM crosssectional images, film thickness were measured as 393.9 and 425.0 nm for the PPy and Al doped PPy thin film, respectively. Electrochemical properties of the deposited polymers are studied by Mott-Schottky analysis and electrochemical impedance spectroscopy. The calculated acceptor concentration is 5.03 × 10 18 m −3 and 5.14 × 10 18 m −3 for PPy and Al:PPy thin film, respectively. EIS analysis are performed to find out the effect of aluminum doping on PPy matrix. An equivalent circuit model is fitted to the EIS data to understand the behavior of coating/electrolyte interface and to determine the values of the circuit elements. Time-dependent self-consistent field and density functional theory based on CAM-B3LYP level with 6-311G(d,p) basis set are used to compute electronic properties such as HOMO and LUMO energies, ionization potential, electron affinity, electronegativity, hardness, softness. Electronic energy levels of the synthesized polymers are represented using the results of Mott-Schottky studies, and the frontier energy levels are also illustrated in this energy diagram to give more detailed explanation.
