“…The time required for absorbance to attain 90 % of the total contrast in a half cycle is the coloration time and the time taken by absorbance to decrease by 90 % of the total contrast in a half cycle is the bleaching time. [45] Although there are no reports on a WO 3 -PEDOP combination to date, nonetheless, our switching times are comparable to the reported values for electrochromic PEDOP or WO 3 . The PEDOP-Au@WO 3 hybrid achieved a contrast considerably higher than that of WO 3 and PEDOP for the same step times under the same applied potential, thus reaffirming the cumulative contributions from PEDOP and WO 3 in increasing the color contrast.…”

A poly(3,4-ethylenedioxypyrrole)-gold nanoparticle (Au)-tungsten oxide (PEDOP-Au@WO3 ) electrochromic supercapacitor electrode capable of optically modulating solar energy while simultaneously storing/releasing energy (in the form of charge) was fabricated for the first time. WO3 fibers, 50 to 200 nm long and 20 to 60 nm wide, were synthesized by a hydrothermal route and were electrophoretically deposited on a conducting substrate. Au nanoparticles and PEDOP were coated over WO3 to yield the PEDOP-Au@WO3 hybrid electrode. The inclusion of Au in the hybrid was confirmed by X-ray diffraction, Raman spectroscopy, and energy-dispersive X-ray analyses. The nanoscale electronic conductivity, coloration efficiency, and transmission contrast of the hybrid were found to be significantly greater than those of pristine WO3 and PEDOP. The hybrid showed a high specific discharge capacitance of 130 F g(-1) during coloration, which was four and ten times greater than the capacitance achieved in WO3 or PEDOP, respectively. We also demonstrate the ability of the PEDOP-Au@WO3 hybrid, relative to pristine PEDOP, to perform as a superior counter electrode in a solar cell, which is attributed to a higher work function. The capacitance and redox switching capability of the hybrid decreases insignificantly with cycling, thus establishing the viability of this multifunction hybrid for next-generation sustainable devices such as electrochromic psuedocapacitors because it can concurrently conserve and store energy.

“…A wide variety of nanocomposites of conjugated polymers with metal oxides such as TiO 2 52, NiO53–55, WO 3 56, 57 and IrO 2 58 have been reported. Conductive nanoparticles such as Ag59, 60, Au59 as well as carbon nanotubes61, 62 and graphene63 have also been incorporated into conjugated polymers to form EC nanocomposites. Bhandari et al64 have reported their studies on the electrochromic properties of the nanocomposite films of Poly(3, 4‐ethylenedioxythiophene) (PEDOT)‐Au‐ CdSe fabricated by first growing a porous PEDOT layer in the ionic liquid 1‐butyl‐1‐methylpyrrolidinium bis (trifluoromethylsulfonyl) imide.…”

Hybrid Materials and Polymer Electrolytes for Electrochromic Device Applications

et al. 2012

Electrochromic (EC) materials and polymer electrolytes are the most imperative and active components in an electrochromic device (ECD). EC materials are able to reversibly change their light absorption properties in a certain wavelength range via redox reactions stimulated by low direct current (dc) potentials of the order of a fraction of volts to a few volts. The redox switching may result in a change in color of the EC materials owing to the generation of new or changes in absorption band in visible region, infrared or even microwave region. In ECDs the electrochromic layers need to be incorporated with supportive components such as electrical contacts and ion conducting electrolytes. The electrolytes play an indispensable role as the prime ionic conduction medium between the electrodes of the EC materials. The expected applications of the electrochromism in numerous fields such as reflective-type display and smart windows/mirrors make these materials of prime importance. In this article we have reviewed several examples from our research work as well as from other researchers' work, describing the recent advancements on the materials that exhibit visible electrochromism and polymer electrolytes for electrochromic devices. The first part of the review is centered on nanostructured inorganic and conjugated polymer-based organic-inorganic hybrid EC materials. The emphasis has been to correlate the structures, morphologies and interfacial interactions of the EC materials to their electronic and ionic properties that influence the EC properties with unique advantages. The second part illustrates the perspectives of polymer electrolytes in electrochromic applications with emphasis on poly (ethylene oxide) (PEO), poly (methyl methacrylate) (PMMA) and polyvinylidene difluoride (PVDF) based polymer electrolytes. The requirements and approaches to optimize the formulation of electrolytes for feasible electrochromic devices have been delineated.

“…The result showed that a 1 wt.% PEDOT-co-PEG coating layer on sulfur cathode presented a higher reversible capacity and better cycling stability than the pure sulfur cathode. Similar to PEDOT, poly(3,4-ethylenedioxypyrrole) (PEDOP) is a kind of conducting polymers with a lower oxidation potential [97]. Mukkabula et al [98] wrapped hydroxyl-functionalized carbon nanotubes/S composite by PEDOP layer to suppress the dissolution and diffusion of polysulfides.…”

With the urgent requirement for high-performance rechargeable Li-S batteries, besides various carbon materials and metal compounds, lots of conducting polymers have been developed and used as components in Li-S batteries. In this review, the synthesis of polyaniline (PANI), polypyrrole (PPy) and polythiophene (PTh) is introduced briefly. Then, the application progress of the three conducting polymers is summarized according to the function in Li-S batteries, including coating layers, conductive hosts, sulfur-containing compounds, separator modifier/functional interlayer, binder and current collector. Finally, according to the current problems of conducting polymers, some practical strategies and potential research directions are put forward. We expect that this review will provide novel design ideas to develop conducting polymer-containing high-performance Li-S batteries.
