Electrochromic strategy for tungsten oxide/polypyrrole hybrid nanofiber materials

Low-Cost Fabrication of High-Performance Fluorinated Polythiophene-Based Vis–NIR Electrochromic Devices toward Deformable Display and Camouflage

“…Compared to typical advanced electrochromic conjugated polymers, ,− the PFPT film exhibits superior overall performances, especially in the NIR region, including excellent optical contrast, high coloration efficiency, fast response time, good memory effect, as well as outstanding stability against both long-term CV and pulse switching cycling (Table b). The advantageous electrochromic performance, making it a promising visible-to-NIR material for various electrochromic devices, is probably attributable to the introduction of a fluorophenyl substituent on the polythiophene backbone, which benefits the formation of a high-quality PFPT film with a better conjugated structure and a more compact chain arrangement.…”

One-Step Synthesis of Polypyrrole Nanofiber Assemblies with Enhanced Electronic Properties: Implications for Next-Generation Organic Electronics

“…Polypyrrole nanofibers (Ppy NFs), due to their unique conducting properties and one-dimensional (1D) nanostructure, are speculated to attain high-efficiency electron transport properties and the capability of structuration, making them promising candidates for the fabrication of advanced nanoelectronics and nanocomposites. − Recently, Ppy NFs have been synthesized and integrated with other nanomaterials, e.g., metals, metal oxides, and nanocarbons, to act as a functional component alone or together with other materials in supercapacitors, electrochromics, electrocatalysts, tissue scaffolds, and soft electronics. − Current synthesis techniques for Ppy NFs include the oxidative template method, electrospinning, and interfacial polymerization. − Core–shell Ppy NFs can be produced by coating Ppy on the electrospun polymer nanofibers, e.g., polyacrylonitrile, and melt-extruded poly (vinyl alcohol-co-ethylene) nanofibers. , However, the insulating polymer core may confine the electron transfer process only in the conductive Ppy coating layer; huge contact resistance may arise on the interface between the Ppy coating and the polymer core. Irregular Ppy particles, rather than nanofibers, would form on the polymer surface during the coating process.…”
