“…[3,4] Consequently, this material has been widely studied for different applications in many domains such as electrochromic devices, rechargeable batteries, protection of metals against corrosion, [5,6] organic light emitting diodes (OLEDs), [7,8] organic photovoltaic cells (OPVs) [9] and dyesensitized solar cells (DSSCs). [10][11][12] Its reversible redox chemistry allows PANI to have mainly three distinguishable oxidation states. Its most common structure is presented as Scheme 1.a, where Y, (0 ≤Y ≤1), corresponds to the ratio of the reduced unit and (1-Y) corresponds to the ratio of the oxidized unit.…”

“…As it is obvious in DTA curves (see inset of Figure ), the maximum rate of decomposition process could be occurred at around 300 °C. The high thermal stability of the ternary nanocomposites could be attributed to the presence of thermal stable TiO 2 nanoparticles and also Cu nanoparticle which could improve PANI/Cu thermal behavior in comparison with pure PANI . Therefore, based on the above descriptions, the addition of PANI/Cu/TiO 2 ternary nanocomposite to the matrix of polyurethane would result in an expected improved thermal stability of the polyurethane film.…”

“…Therefore, PANI/noble metal nanocomposite would be a good way to exploit exceptional behavior of conducting polymers along with attractive characteristics of noble metal nanoparticles . PANI/Cu nanocomposites have been studied, aiming to produce materials with enhanced antibacterial activity, sensitivity, electrochemical activity, and so on, alongside improved electrical conductivity in comparison with pristine PANI . Therefore, these improved properties could be used to make PANI/Cu nanocomposites a good choice to be used as an additive in the production of multifunctional antibacterial and antistatic organic coatings.…”

Surfaces with antibacterial and antistatic functionalities are one of the new demands of todays' industry. Therefore, a facile method for the preparation of multifunctional polyaniline/copper/TiO2 (PANI/Cu/TiO2) ternary nanocomposite based on in situ polymerization is presented. This nanocomposite was characterized through the different techniques and was utilized for induction of antibacterial and antistatic properties in polyurethane coatings. Measurement of the conductivity of PANI/Cu/TiO2 ternary nanocomposite indicated higher electrical conductivity of this nanocomposite compared to pure PANI. The antibacterial activity of the modified polyurethane coatings was tested against Gram‐positive and Gram‐negative bacteria which led to remarkable reduction in bacterial growth. Besides, it was observed that polyurethane coating with 2 wt % content of ternary nanocomposite has a surface electrical resistance equal 4 × 108 Ω/sq which acquires surface electrical resistance of standard antistatic coatings. The final coatings were also characterized in terms of thermal and mechanical properties to investigate the effect of the ternary nanocomposite on improvement of these properties. © 2020 Wiley Periodicals, Inc.

Abstract. Dye sensitized solar cells (DSSCs) are most promising devices among third-generation solar cells because of low cost, easy production, environmental friendliness, and relatively high conversion efficiency. Counter electrode (CE), which is an important component in DSSCs, functions as an electron transfer agent as well as the regenerator of redox couple. Hitherto, various methods and materials were used to prepare different counter electrodes.Among these materials, conducting polymers have been widely investigated and employed in various applications such as sensors, supercapacitors, energy storage devices, DSSCs and others. In this study, Polythiophene (PTh) conducting polymer was successfully synthesized by electrochemical deposition method, and employed as an alternative to expensive platinum (Pt) CE for DSSC. Besides, PTh conducting polymer was electrochemically deposited via cyclic voltammetry method on FTO substrates. The morphology of the PTh film was characterized by SEM and AFM. Finally, the photovoltaic performance of PTh CE based DSSC was compared with PEDOT CE based device. This new concept-along with promising electrocatalytic activity and facile electron transfer-provides a new approach to enhance the photovoltaic performances of Pt-free DSSCs.
