“…Moreover, in this area of research, intrinsically conducting and semiconducting polymeric nanospheres captured the attention of the scientific community in the past few years [19][20][21]. Recently, poly(3,4-ethylenedioxythiophene) (PEDOT) hollowed nanospheres were synthesized by Zhang et al for applications into electrochromic systems [22]. The results showed that, for nanospheres with diameter around 100 nm, the ion transport in the material was promoted, with respect to the denser and more compact bare PEDOT, underling the importance of tuning the dimensions of the particles for in PEDOT based system.…”

<div><div><div><p>Electrically conducting nanospheres of poly-(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) with tailored size, were prepared by a one-step method. To fabricate the nanostructures, PEDOT:PSS was dissolved in ethylene glycol using a novel strategy and the solution was precipitated in deionized water. The proposed fabrication route allowed to obtain a water-based dispersion of monodisperse nanospheres with good optical properties. To determine physical properties of the nanospheres, we followed a nanoscale approach, using Atomic Force Microscopy (AFM). Our nanoscale mechanical and electrical investigations showed that the nanospheres preserved good physical properties, compared to the commercial product. Moreover, the local studies indicated that the confinement imposed by the spherical shape can lead into a different arrangement of the PSS and PEDOT phases. In particular, we envisaged nanospheres composed by a PEDOT-rich surface, responsible for the good electrical conductivity of the nanostructures.</p></div></div></div>

“…More commonly, EDOT-based polymers have been used as the primary electrochromic material due to their stability, oxidative state conductive properties, and coloration efficiency . PEDOT films are typically synthesized and fabricated using electrostatic deposition, electropolymerizations, and/or radical polymerization . However, challenges in applicability typically surround the low solubility of the polymer in fabricating solvents, thus hindering thin film preparation and overall device performance .…”

The electrochromic properties and application of electronically conducting polymers (ECPs) (PTRPZ-EDOT) consisting of a 3,4ethylenedioxythiophene (EDOT) and the heteroacene-based molecular scaffold, 6H-pyrrolo[3,2-b:4,5-b′] bis [1,4] benzothiazine (TRPZ), are reported. Known for its high electron mobility and conducting properties, the novel TRPZ scaffold was synthesized to possess two EDOT molecules termini affording TRPZ-EDOT. Electropolymerization of TRPZ-EDOT resulted in remarkable spectroscopic and conductive properties suitable for electrochromic device fabrication. Using atomic force microscopy (AFM), the average surface roughness and surface topography of PTRPZ-EDOT polymer thin films were determined. Spectroelectrochemical data showed that the polymer achieved switching times of 4.07 (coloration) and 0.47 s (bleaching) at 539 nm. The PTRPZ-EDOT film exhibits an optical contrast of 36−44% at 539 nm between its neutral and colored states, respectively. The NIR region from 1000 to 1700 nm shows the appearance of charge carrier bands with a 0−1 V potential range. An electrochromic device was successfully fabricated from PTRPZ-EDOT, showcasing the potential and applicability of the polymer material for advanced technologies such as smart windows, flexible electrochromic screens, and energy storage devices.
