The Flexible Electrochromic Device That Turns Blue Under Both Positive and Negative Application Voltages

Electrochromic device with Prussian blue and HPC-based electrolyte

Given the importance of the development of electrochromic devices (ECDs) for technological applications small devices with Prussian blue (PB)/hydroxypropyl cellulose (HPC) electrolyte/CeO2TiO2 configuration were assembled and characterized. The films of PB were obtained galvanostaticaly by applying 0.45 mA for 300 s. The cyclic voltammetry, in 1 mol L 1 KCl solution, of these films showed a red...

Development of Flexible Electrochromic Device with Thin Film Configuration

Graphene based flexible electrochromic devices

Graphene emerges as a viable material for optoelectronics because of its broad optical response and gate-tunable properties. For practical applications, however, single layer graphene has performance limits due to its small optical absorption defined by fundamental constants. Here, we demonstrated a new class of flexible electrochromic devices using multilayer graphene (MLG) which simultaneousl...

Ultrafast switching of an electrochromic device based on layered double hydroxide/Prussian blue multilayered films.

Electrochromic materials are the most important and essential components in an electrochromic device. Herein, we fabricated high-performance electrochromic films based on exfoliated layered double hydroxide (LDH) nanosheets and Prussian blue (PB) nanoparticles via the layer-by-layer assembly technique. X-ray diffraction and UV-vis absorption spectroscopy indicate a periodic layered structure wi...
