“…However, inorganic electrochromic materials suffer from many disadvantages, such as long response time, high cost, high oxidative potential, and poor cycling stability . Recently, organic electrochromic materials have been extensively studied for their electrochromic properties owing to their low cost, short response time, long cycling stability, and low operation potential. − …”

On the basis of nanocellulose obtained by acidic swelling and ultrasonication, rodlike nanocellulose/polyaniline nanocomposites with a core-shell structure have been prepared via in situ polymerization. Compared to pure polyaniline, the nanocomposites show superior film-forming properties, and the prepared nanocomposite films demonstrate excellent electrochemical and electrochromic properties in electrolyte solution. Nanocomposite films, especially the one prepared with 40% polyaniline coated nanocomposite, exhibited faster response time (1.5 s for bleaching and 1.0 s for coloring), higher optical contrast (62.9%), higher coloration efficiency (206.2 cm/C), and more remarkable switching stability (over 500 cycles). These novel nanocellulose-based nanorod network films are promising novel electrochromic materials with excellent properties.

“…Hernández‐Guzmán et al combined PANI with poly (3‐hexylthiophene) to fabricate a complementary ECD, which exhibited absorption at greater wavelengths near the NIR region (750–1200 nm) due to the appearance of bipolarons charge carriers in the doping process which further caused the changes of band‐gap structures. [ 58 ] Li et al prepared a bowl‐like PANI film by electrodeposition and monolayer colloidal crystal template. [ 59 ] The higher coloration efficiency (118.2 cm 2 .C −1 ), larger optical transmittance modulation (52.1% at 740 nm), and faster‐switching speed (colored/bleached time of 1.45/0.62 s) benefited from the unique macroporous structure, which not only offered increased intercalation sites but also shortened diffusion distances for ions.…”

Smart windows refer to those which can dynamically modulate the transmitted light by changing their colors. Dual-band electrochromic materials (ECMs) refer to materials that can change their colors and regulate light transmission in both visible (VIS) and infrared (IR) regions under different voltages. The dual-band ECMs-based building windows can thus regulate the indoor temperature to reduce the energy consumption for heating and airconditioning systems. Therefore, the wide application of ECMs in building windows will contribute a lot to establishing an energy-saving society. During the past decades, enormous efforts have been made to improve the performance of dual-band ECMs. This review presents a summary of the recent progress of dual-band ECMs, focusing on their modulation mechanism, material design, and performance optimization. Finally, the challenges and outlook of dual-band ECMs are also discussed.
