Water processable Prussian blue–polyaniline:polystyrene sulfonate nanocomposite (PB–PANI:PSS) for multi-color electrochromic applications

Abstract

The novel PB–PANI:PSS thin film shows multi-color electrochromism at −0.5 V (transparent), +0.2 V (green), and +0.5 V (blue-green).

Multifunctional Prussian blue analogous@polyaniline core–shell nanocubes for lithium storage and overall water splitting

“…For pure PANI, the adsorption bands at 1144, 1307, 1496 and 1581 cm À1 can be assigned to the C-H plane-bending vibration, C-N stretching vibration, C]C stretching of benzenoid ring, and C]C stretching of quinoid rings of PANI, respectively. [37][38][39][40][41] By comparison, it is clearly seen that the FT-IR spectrum of PBAs@PANI nanocubes also exhibits these adsorption bands, indicating the presence of PANI in asprepared PBAs@PANI nanocubes. 42 As for Raman spectrum of pure PANI (Fig.…”

Distribution of dopant ions around poly(3,4-ethylenedioxythiophene) chains: a theoretical study

“…These materials have received considerable interest because of their potential applications in technological fields, such as electronics, biomedical engineering, and optics. 1 For example, in the last years they have been proposed for organic batteries, 2,3 biosensors, 4,5 protective coatings for metals, 6,7 electrochromic devices, 8,9 organic light emitting diodes (LEDs), 10 drug delivery sysems 11 and tissue scaffolds. 12,13 Among the many properties of CPs, the more remarkable are the electrical conductivity and the electrochemical activity (i.e.…”

Green fabrication of a complementary electrochromic device using water-based ink containing nanoparticles of WO3 and Prussian blue

“…There are various EC materials: transition metal oxides [19][20][21] such as WO 3 , 22-24 metal hexacyanoferrate (MHCF) complexes, [25][26][27] metal hydrides, 9,10 and organic polymers. [28][29][30][31][32][33] Among the EC materials, tungsten oxide, WO 3 , is a key material. The WO 3 -based ECD shows blue-bleached switching.…”
