“…A very complete review of these kinds of structures can be found in 331 . Even electrochemical polymerization can be used to grow inside the alumina templates certain conductive polymers, as it was done with PEDOT inside 3D AAOs to obtain a 3D interconnected free-standing network of 20 nm diameter vertical nanowires connected by 10 nm diameter wires, maintaining the semiconducting properties of the polymer 62 . These 3D structures have also been filled with polyethylene by melting infiltration, obtaining hydrophilic, flexible nanostructured macroscopic polymeric structures with tunable iridescent coloring (given that they act as Bragg refractors, being the replica of the 3D alumina templates, which color can be tuned by changing their fabrication parameters, as it was already discussed in section 7.1) 61 .…”

“…As an example, the use of nanostructurated electrodes of conducting polymers in supercapacitors increases the surface area, thus increasing the capacitance of the nal device. 10,17,18 In the case of thermoelectric polymers, the thermal conductivity can be tailored through nanowire structuration due to phonon scattering. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 can be used for the preparation of coatings for specic applications, such as electrodes in supercapacitors 31 or solar cells.…”

The synthesis of conducting polymer nanoparticles by oxidative polymerization can be a challenge, because the addition of oxidizers may compromise the colloidal stability of the system. In this work, we report the successful synthesis poly(3,4-ethylenedioxythiophene) (PEDOT) nanoparticles by means of miniemulsion polymerization. We study the role of oxidizing agents (iron(iii) p-toluenesulfonate and hydrogen peroxide) during the particle formation particles and in the electric properties. The presence hydrogen peroxide is demonstrated to be crucial in the macroscopic stability of the suspensions and the morphology of the resulting nanoparticles. The obtained suspensions, containing particles of diameters of around 30 nm, are stable for several months. The electrical conductivity increases with increasing the content of iron(iii) p-toluenesulfonate, but it decreases with addition of hydrogen peroxide, which can be explained by secondary reactions in the polymerization process.

“…In Figure 4c, the band of C=C symmetrical stretching in the thiophene ring is at 1444 cm −1 in PEDOT and shifts to 1426 cm −1 in the PEDOT micro-helix [84,85]. The bands of asymmetrical C=C stretching are at 1506 cm −1 for both PEDOT and the PEDOT micro-helix [86,87]. The peak at 1361 cm −1 that is related to C–C stretching is only observed in the PEDOT micro-helix [87].…”

Abstract:As one of the most interesting naturally-occurring geometries, micro-helical structures have attracted attention due to their potential applications in fabricating biomedical and microelectronic devices. Conventional processing techniques for manufacturing micro-helices are likely to be limited in cost and mass-productivity, while Spirulina, which shows natural fine micro-helical forms, can be easily mass-reproduced at an extremely low cost. Furthermore, considering the extensive utility of conducting polymers, it is intriguing to synthesize conducting polymer micro-helices. In this study, PPy (polypyrrole), PANI (polyaniline), and PEDOT (poly(3,4-ethylenedioxythiophene)) micro-helices were fabricated using Spirulina platensis as a bio-template. The successful formations of the conducting polymer micro-helix were confirmed using scanning electron microscopy (SEM). Fourier transform infrared spectroscopy (FTIR) and Raman and X-ray diffraction (XRD) were employed to characterize the molecular structures of the conducting polymer in micro-helical forms. In the electrochemical characterization, the optimized specific capacitances for the PPy micro-helix, the PANI micro-helix, and the PEDOT micro-helix were found to be 234 F/g, 238 F/g at the scan rate of 5 mV/s, and 106.4 F/g at the scan rate of 10 mV/s, respectively. Therefore, it could be expected that other conducting polymer micro-helices with Spirulina as a bio-template could be also easily synthesized for various applications.
