“…Also, we noticed a lack of peaks around = 600 nm, which indicated that the PEDOT chains preserved their oxidation state as previously reported by Heuer et al [48]. Finally, the UV-Vis signal of the PEDOT:PSS nanospheres for > 900 nm remained constant, also supporting the fact that the nanospheres fabrication process did not alter the chemical nature of the PEDOT:PSS complex [49][50].…”

<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>

“…Pre-treatment methods involve the simple addition of polar, protic, and aprotic organic solvents miscible with water, such as N-methyl-2-pyrrolidone (NMP), dimethyl sulfoxide (DMSO), N,N-dimethylformamide (DMF), and ethylene glycol (EG) [32,33,[35][36][37], or of organic compounds that get dissolved in water, such as sorbitol [33,38,39], as well as the incorporation of low-viscosity and transparent ionic liquids like 1-ethyl-3-methylimidazolium tetracyanoborate (EMIM BTI) [16,29] and ionic/non-ionic surfactants like cetrimonium bromide (CTAB), sodium dodecyl sulphate (SDS), and polyethylene glycol p-(1,1,3,3-tetramethylbutyl)-phenyl ethers (Triton X-100) into the aqueous dispersion of PEDOT:PSS [11,40]. The addition of pre-treatment agents (dopants) into the polymer solution will substantially affect the electrical conductivity, transmittance, and morphology of the formed films.…”

An organic conductive polymer, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT: PSS), is an attractive candidate for a low-cost, low-temperature, and solution-processed electrode material for achieving high-performance flexible and stretchable thin-film devices. Unlike most organic materials, this water-soluble conjugated polymer is highly stable against chemical and physical exposure. It exhibits the most superior mechanical flexibility and the highest optical transparency and electrical conductivity among all organic conductors. Therefore, this conductive polymer is among the most promising alternatives to the expensive, rigid, and brittle metal oxide-and even metal-based electrode materials, such as indium tin oxide (ITO) and gold, in the future solutionprocessed electronic devices. Nevertheless, the intrinsic conductivity of PEDOT:PSS is typically below 1 S cm −1 , which is too low for such devices. Fortunately, the material properties of PEDOT:PSS, including its conductivity, are easily tuned by employing a large number of simple approaches. In this paper, the reports on the successful application of PEDOT:PSS to a wide range of solution-processed organic devices, such as organic light-emitting diodes (OLEDs), organic thin-film transistors (OTFTs), and organic photovoltaics (OPVs), are reviewed. The recent progress in the development of highly conductive PEDOT:PSS-based films for electrode applications in the field of organic electronics is the main focus of the discussion herein.

“…Even though PEDOT has substantial electrical conductivity, it is insoluble in drinking water, rendering it difficult to process. [ 47 ] To enhance the solubility and dispersibility of PEDOT, it is usually doped with a water‐soluble polyelectrolyte, PSS. The presence of sulfonate (SO

Rapid technological advancements in flexible nanoelectronics have fueled the need for high‐performance materials with advanced structural architectures and superior properties. In this regard, conducting polymer nanocomposites are at the forefront of current innovative research owing to their excellent properties. Among these sets of unique materials, poly(3,4‐ethylenedioxythiophene)‐poly(styrenesulfonic acid) (PEDOT:PSS) nanocomposites continue to pave the way in several applications including those entailing thermoelectricity, transparent electrodes, photovoltaics, technical coatings, lighting, sensing, bioelectronics, hole transport layers, interconnectors, electroactive layers, and motion‐sensing conductors. The versatility and intriguing properties of these composites, particularly with 2D nanomaterials, have garnered significant attention from academia as well as industry. Therefore, in this review, the latest developments in PEDOT:PSS nanocomposites with graphene and its derivatives are focused on.
