Dark Blue

Poly(3,4-ethylenedi-oxythiophene) (PEDOT) derivatives conducting polymers are known for their great electrochromic (EC) properties offering a reversible blue switch under an applied voltage. Characterizations of symmetrical EC devices, built on combinations of PEDOT thin films, deposited with a bar coater from commercial inks, and separated by a lithium-based ionic membrane, show highest performance for 800 nm thickness. Tuning of the color is further achieved by mixing the PEDOT film with oxides. Taking, in particular, the example of optically inactive iron oxide Fe2O3, a dark blue to reddish switch, of which intensity depends on the oxide content, is reported. Careful evaluation of the chromaticity parameters L*, a*, and b*, with oxidizing/reducing potentials, evidences a possible monitoring of the bluish tint.

In the present study, the electrosynthesis and the electrochemical characterization of azo dyes doped poly(3,4-ethylenedioxythiophene (PEDOT) were described. PEDOT film was electrochemically deposited onto indium doped tin oxide (ITO) coated/glass electrode, following azo dyes adsorption. The electropolymerized-PEDOT films on ITO glass were doped with various azo dyes; 4-Phenylazo-2-phenyliminomethyl-phenol (PAPM), 4-Phenylazo-2-(p-tolyimino-methyl)-phenol (PATM) and 4-[(2-Hydroxy-5-phenylazo-benzylidene)-amino]-benzenesulfonic acid (HPAB). The structures of azo dyes-doped PEDOT were characterized via cycle voltammograms and electrochemical impedance spectroscopy (EIS). Diverse doping counterions have a significant influence on the electrochemical behaviour of electropolymerized-PEDOT film. The electropolymerized-PEDOT doped by HPAB (PEDOT-HPAB) film possesses higher electrochemical activity than other azo dye-doped PEDOT composites. The main characteristics of PEDOT-azo dyes films contain uniformity, durability, and adherent on ITO electrodes, which are better when it is compared to PEDOT film.

Pedot Film

Conducting poly (3, 4-ethylenedioxy-thiophene) (PEDOT) thin film was prepared onto gold electrode by electrodepositing from aqueous electrolyte. Glucose oxidase (Gox) was further immobilized on the PEDOT/Au by physical adsorption. The morphology the modified electrode was investigated by FE-SEM. In phosphate buffer medium (0.1mol·L-1 pH 5.5), cyclic voltmetric results indicated that GOx can be immobilized on the PEDOT film, and the biological activation of GOx was retained. A direct electron transfer was found between immobilized GOx and electrode, which suggested that the PEDOT film could not only supply a platform for enzyme immobilization but also offer a effectively electrical contact with the active sites of enzyme.
