Influence of polyethylene glycol template on microstructure and electrochromic properties of tungsten oxide

Fast Switching Electrochromic Devices Containing Optimized BEMA/PEGMA Gel Polymer Electrolytes

“…The typical current versus time profile for a single-EC-electrode device is shown in Figure 6. In agreement with the literature [1,4,5], the electrochemical insertion of lithium cations into WO 3 occurs in the selected potential range according to the following reaction:…”

“…One of the first candidates studied for such application was tungsten oxide (WO 3 ) [2][3][4]. In particular, the surfactant assisted electrochemical synthesis of WO 3 [5] is one of the most promising methods for the production of nanostructured powders suitable for inks formulations. The counter electrode, in general, is considered the limiting factor in the EC device [6].…”

Influence of Zn doping on structural, optical and photocatalytic activity of WO3 nanoparticles by a novel microwave irradiation technique

“…WO 3 , an n-type semiconductor with an excellent electrochromic, photochromic and gasochromic properties has been extensively used in variety of applications, including gas and temperature sensing, catalysis, electrochromic windows and displays, flat panel displays, solar energy devices and so on [3]. Many processes have been developed for the synthesis of WO 3 nanostructures, e.g., hydrothermal route [4], surfactant mediated method [5] sol-gel [6], chemical co precipitation [7], acidification method [8], and electrodeposition method [9]. Compared with the above processes, the microwave method has sparked much interest due to their operation simplicity, effective, low-cost route to synthesis, less time consuming (about 10 min), and for large-scale production [10].…”

Ionically conducting Er3+-doped DNA-based biomembranes for electrochromic devices

“…The main advantages of SPEs when compared with ceramic systems are: (i) easy processing such as flexible thin films and easy processing on large areas; (ii) no need for separators; (iii) good thermal and potential stability windows; (iv) wide operating temperature range; (v) low chemical reactivity; (vi) good safety as well as good optical contrast, memory effect, image stability, tolerance to shock, vibration and mechanical deformation properties; (vii) possibility to act as binder because they facilitate the good electrical contact with the electrodes/good adherence to the neighbouring electrochromic layers leading to compact large area device fabrication and (viii) frequently enhanced endurance to varying electrode volume changes cycling [24][25][26][27].…”
