“…The electrical conductivity of the PPy:PSS films on a silicon wafer ( Figure 3E) for the two synthetized nanosuspensions presented values in the range of polypyrrole conductivity films [47,48]. As expected, when a PSS of higher molecular weight is used during PPy:PSS synthesis, the conductivity value increases, most likely due to the doping effect of the extra sulfonate groups [49]. The characterization of PP nanosuspensions reflects the potential of nanosuspensions as a method to obtain conductive films with easily modifiable properties.…”

In this paper, we report a one-step method to obtain conductive polypyrrole thin films on flexible substrates. To do this, substrates were modified through allylamine plasma grafting to create a high amount of reactive amine groups on PDMS surface. These groups are used during polypyrrole particle synthesis as anchoring points to immobilize the polymeric chains on the substrate during polymerization. Surface morphology of polypyrrole thin films are modified, tailoring the polyelectrolyte used in the polypyrrole synthesis obtaining different shapes of nanoparticles that conform to the film. Depending on the polyelectrolyte molecular weight, the shape of polypyrrole particles go from globular (500 nm diameter) to a more constructed and elongated shape. The films obtained with this methodology reflected great stability under simple bending as well as good conductivity values (between 2.2 ± 0.7 S/m to 5.6 ± 0.2 S/cm).

“…All of the synthesized PEDOT:PSS samples show a spherical shape as PSS is an anion polymeric surfactant which generally forms spherical micelles. 42 24 The slight increases in particle size of the PEDOT:PSS synthesized in the acid solutions possibly involved the interaction between PSS micelles and acid ions inducing larger particle sizes. 43 The thermal stability of PEDOT:PSS particles was investigated using TGA under nitrogen flow as shown in Fig.…”

The poly (3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) synthesis conditions were refined to obtain extremely high electrical conductivity. PEDOT:PSS was synthesized by chemical oxidative polymerization under the effects of acid types and concentrations, EDOT:PSS weight ratio, and surfactant types and concentrations. The PEDOT:PSS synthesized with EDOT:PSS weight ratio of 0.5:5.5 in 0.1 mol L −1 HClO 4 provided the highest electrical conductivity of 1.04 × 10 4 ± 188 S cm −1 , not previously reported. The enhanced electrical conductivity can be attributed to the combinatorial primary doping by selective ions (ClO 4 − , PSS − , SO 4 2−) generating a suitable PEDOT:PSS structure with high carrier number and electron mobility, as consistently verified using Fourier transform infrared spectroscopy, UV-visible spectrometry, X-ray photoelectron spectrometry and thermogravimetric analysis. The refined synthesis opens a new route for PEDOT:PSS nanoparticles to be used in various electronic applications which require the starting nontoxic organic material to be highly conductive.

“…1(c), the bands appearing at 1536 cm À1 and 1446 cm À1 are associated with the fundamental vibrations of the PPY ring. 47 The absorption bands at approximately 1280 cm À1 , 1134 cm À1 , and 1024 cm À1 are attributed to the C-N stretching vibration and the QC-H inplane vibration. The peaks observed at 963 cm À1 , 843 cm À1 , and 767 cm À1 confirm the polymerization of pyrrole, as shown in Fig.…”
