“…Tables S4 and S5 † list the comparison of the present work with previously reported various electrochromic electrodes/devices. [10][11][12]14,[16][17][18]21,22,24,[39][40][41][42][43][67][68][69][70][71][72][73][74][75] Notably, among the newly reported EESDs, the EAZS has the most outstanding electrochemical cycle life, which is the most promising candidate for applications in smart portable electronic devices and fastcharging electric-buses. Additionally, we summarize the focusing strategies and associated parameters of the EAZS (Fig.…”

Reversible Dual-Stimuli-Responsive Chromic Transparent Wood Biocomposites for Smart Window Applications

“…Wood is a renewable natural resource and interesting substrate for implementing in advanced materials due to its hierarchal porous structure from nano- to microscale, high mechanical strength, and the presence of surface functional groups suitable for altering the chemistry or imbibing functional moieties. − Transparent wood (TW) has recently emerged as a biocomposite material for applications involving high light transmittance with pliable optical characteristics. , Wood is made transparent by removing light-absorbing chromophores and filling the voids with a polymer of refractive index close to that of the wood substrate. − Although transparent wood was initially developed for the analysis of wood anatomy, it is now considered as wood-based composite for advanced functional (and simultaneously load-bearing) applications, such as white-light-emitting diodes, , solar cells, , and luminescent , and heat shielding , applications in panels and windows. Smart electrodes for electrochromic properties of reversible control of optical properties on application of applied voltage are extending usefulness in various fields, especially for fabricating solar cells. − Electrochromic TW was fabricated by coating poly­(3,4-ethylene­dioxythiophene):poly­(styrene­sulfonate) (PEDOT:PSS), which can switch to a coloration efficiency of 590 cm 2 C –1 . TW with low thermal conductivity, low specific density, enhanced toughness, and shatterproof features can be considered as good candidate for window-like structures instead of brittle glass. , …”

Toward Durably Flexible Nickel Oxide Electrochromic Film by Covering an 18 nm Zinc Tin Oxide Buffer Layer

“…However, the conventional nickel oxide film for the ECD suffers from several inherent shortcomings in low coloring efficiency, small optical modulation amplitude, poor cycling durability, and yellow color in the bleached state, − which limit its commercialized application. To further improve the EC performance of nickel oxide film, a large number of works have been carried out. , It has been found that doping and codoping other elements, such as Li, Co, Ti, W, Cu, and Si, into the nickel oxide matrix can markedly improve the EC properties. ,− Recently, we conducted a synergistic process containing Si–Li codoping and followed 400 °C rapid thermal annealing (RTA) treatment to ensure nickel oxide film with superior EC properties in higher bleached transmittance (93.3% at 550 nm), larger optical modulation (37.0%), enhanced charge capacity (14.8 mC·cm –2 ), and improved electrochemical stability . This kind of nickel oxide material with Si–Li codoping was named as the SLNO, which was considered to have huge potential for future large area commercialized application in ECDs.…”
