Ultrafast black-color tunability of electrochromic dimming films using cobalt polyoxometalate-anchored nickel oxide nanoparticles

Abstract

A black color tunability of electrochromic (EC) dimming device was explored using cobalt polyoxometalate (CoPW)-anchored nickel oxide nanoparticles (CoNiOx), The CoNiOx layer enhanced not only the anodic EC properties of...

Ultrafast black color tunability of electrochromic dimming films using polyoxometalate-anchored metal oxide nanoparticles

“…The crystals were collected by filtration, quickly washed with water and air dried to give K10[M4(H2O)2(PW9O34)2]. TBAPWMOx composite was prepared from a mixture of K10[M4(H2O)2(PW9O34)2] and tetrabutylammonium bromide (TBABr) [7].…”

“…As the working electrode of ECD, a conjugated polymer (PRBr) film was coated on ITO glass through an electropolymerization process using 3,3-bis(bromomethyl)-3,4-dihydro-2H-thieno-[3,4-b][1,4]dioxepine and 0.5 M LiBF4 in propylene carbonate with a 3-electrode cyclic voltammetry system at a voltage range between -0.4 V and 1.85 V at a scan rate of 100 mV/s for 10 cycles using ITO glass, stainless steel and Ag/AgCl as a working electrode (WE), a counter (CE) and reference electrode (RE) [7]. As the counter electrode of the electrochromic device, metal oxide [MOx] was coated on FTO glass through a solution casting method.…”

“…The space between the WE and CE was filled with 1M LiTFSI contained BMIMTFSI and sealed with a clip press according to previous reports. [7]…”

Recent Advance in Electrochromic Materials and Devices for Display Applications

“…In recent years, the developments on ECDs have facilitated the design and application of EC displays. [52,54,[95][96][97][98][99][100] EC multilayer film usually consists of at least two layers of ECMs and one layer of electrolyte. Multiple color changes are achieved by controlling the voltage between the different layers of ECDs.…”
