“…The samples' electrochemical properties were measured in a three‐electrode system. ITO‐coated glass printed with EC ink (PEDOT:PSS or PEDOT:PSS/MWCNTs) was used as the working electrode, while an ITO‐coated glass without ink was used as both the counter and reference electrodes . Cyclic voltammograms were obtained from −2.5 to +2.5 V at a scan rate of 100 mV/s.…”

A high cycling stability material and an additive manufacturing method are reported for the fabrication of solid electrochromic devices. The poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate)/multi‐walled carbon nanotube (PEDOT:PSS/MWCNT) nanocomposites were synthesized via in situ polymerization. A carboxymethyl cellulose gel was used as the ink vehicle for screen printing. The electrochromic (EC) performance of films patterned by screen printing was also examined. The results of characterization indicate that strong interfacial interactions occurred between PEDOT:PSS and the MWCNTs and the MWCNTs formed a network in these conducting polymers film, so the composite was more conductive than pure PEDOT:PSS. Devices containing PEDOT:PSS/MWCNTs were more stable after 1000 cycles, exhibited higher rate of ion exchange and faster increases in current. The composite containing 0.3 wt % MWCNTs also had a 23% higher color contrast (ΔE*) than pure PEDOT:PSS at 2.5 V applied voltages. The EC inks with well printability not only can be used to print large area films, but also can print fine lines and pixel‐type dots in displays. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

“…The surface microstructures of the films were investigated using a scanning electron microscope (SEM, ZEISS, Auriga-39-50, Oberkochen, Germany). The properties of the electrochromic films were characterized in a two-electrode cell with an electrochemical analyzer (CHI, 6273B, Austin, TX, USA), in which, the Li x W 1−x O/ITO/glass was a working electrode and a common ITO/glass was simultaneously a counter electrode and a reference electrode [9]. The atomic composition of the material was analyzed by Electron Spectroscopy for Chemical Analysis (ESCA, JEOL, JAMP-9500F, Tokyo, Japan) [10].…”

In this study, xLi 2 O-(1−x)WO 3 powders were mixed with WO 3 and Li 2 O and pressed into target pellets to fabricate electrochromic films on indium tin oxide (ITO) glasses prepared by electron beam evaporation under the parameters of room temperature, and thicknesses of about 530 nm. It was expected that the amount of charge stored in the electrochromic devices (ECDs) could be enhanced by using the doping method in the cathode materials. The experimental results show that as the composition of Li 0.18 W 0.82 O 2.6 powder was formed, the optimal characteristics of ECD can be obtained. In which, as a voltage of 3.5 V was applied on ECD, a transmittance change (∆T%) of 53.1%, an optical density (∆OD) of 0.502, an intercalation charge (Q) of 12.9 mC/cm 2 and a coloration efficiency (η) of 41.6 cm 2 /C at a wavelength of 550 nm can be achieved. These results demonstrate that Li 2 O doping in WO 3 films could effectively improve the coloration and electrochromic properties of ECD devices.

“…Polymer electrolytes are important for technology because they can be used in the fabrication of special devices, such as electrochromic 1,2 devices, lithium batteries [3][4][5] , supercapacitors 6 , sensors 7,8 , and fuel cell polymer electrolyte membranes (PEM) [9][10][11] . A large number of materials have been tested in this area, but conducting polymers and gel polymer electrolytes stand out.…”

Materials based on a mixture of poly(vinylidene fluoride) (PVDF), poly(2-hydroxyethyl methacrylate) (PHEMA) and LiClO 4 were produced to evaluate their ionic behavior and morphological structure to determine if they can be used as an electrolyte in electrical devices. FTIR chemical analysis results indicated the presence of interactions between PVDF, PHEMA and LiClO 4 . MDSC results showed that the transition temperatures of the polymers shifted to higher temperatures for systems containing high concentrations of each polymer. SEM images indicated that there was some miscibility between the polymers especially for the 25 and 75 wt. % compositions. In terms of the electrical performance, the ionic conductivity level of the electrolyte could be controlled by changing the composition of the system.
