Novel polyaniline (PANI) nanofiber counter electrodes (CEs) modified with different transition metal ions were synthesized and showed remarkable catalytic activity for dye‐sensitized solar cells (DSSCs). The PANI nanofiber–transition metal ion electrodes were characterized by using Fourier transform infrared spectroscopy, scanning electron microscopy, current density–voltage curves, energy‐dispersive X‐ray spectroscopy, cyclic voltammetry, electrochemical impedance spectroscopy, and Tafel polarization plots. The PANI CEs modified with Ni2+ and Co2+ exhibited low charge‐transfer and series resistances, which indicate high electrocatalytic activity toward the iodide redox shuttle. In contrast, the PANI CE modified with Mn2+ did not show much difference in its catalytic behavior, whereas the PANI—Cu2+ CE showed reduced electrochemical performance. The photovoltaic performances of the DSSCs based on the PANI–Ni2+ and PANI–Co2+ CEs were evaluated and they were found to exhibit power conversion efficiency of 4.70 and 4.57 %, higher than that of the pristine PANI‐CE‐based device (3.87 %). These easily fabricated PANI–metal composites with improved electrochemical activities are promising CEs for DSSCs to replace expensive Pt.

Tuning of hole transport and optical properties were accomplished in polyaniline incorporated flexible paper during vapor phase polymerization process. Vapor phase polymerization of aniline using FeCl3 as polymerizing agent was done in a reaction chamber, where the concentration of FeCl3 on paper played the key role in tuning its properties. The energy band gap and electrical conductivity of the polyaniline incorporated paper have been tuned effectively during the polymerization process. The band gap changes from 2.45 eV to 2.65 eV, when the electrical sheet resistance varied from 1.0 ×105 Ω/◻ to 4.33 ×107 Ω/◻ in response to the different FeCl3 concentration. The electrical sheet resistance can be tuned within a range of two order of its value. Polymer‐based electronic materials with outstanding electrical conductivity due to their delocalized molecular orbitals are of great interest in the recent development of materials chemistry and physics. Paper being a flexible substrate and incorporated with a hole transporting medium like polyaniline in its emeraldine base form will find its significant role in designing flexible electronic devices.

“…PAni nanostructures can be synthesized with zero dimensions (e.g., nanospheres [3] ), one dimension (e.g., nanofibers [4] , nanorods [5] , and nanotubes [6] ), and two dimensions (e.g., nanobelts [7] and nanosheets [8] ). PAni nanostructures have been widely investigated because they combine the unique characteristics of a conventional polymer with the quantum effects of nanomaterials [9,10] .…”

Cashew nut shell liquid, a valuable raw material for generating semiconductive polyaniline nanofibers

et al. 2018

View full text Add to dashboard Cite

Cashew nut shell liquid (CNSL) is an abundant and renewable by-product of the cashew nut industry. It appears to be a valuable raw material for generating semiconductive polyaniline (PAni) nanomaterial with enhanced thermal stability and well-defined nanofiber morphology following a polymerization dispersion process. This study confirms that CNSL acts as a soft template during PAni synthesis, leading to an improvement in the nanofiber aspect. CNSL also improves the thermal stability of the PAni nanomaterial. Moreover, CNSL is an effective surfactant that promotes and stabilizes the dispersion of PAni nanofibers within water, allowing the more ecofriendly preparation of PAni nanomaterial by substituting the commonly used organic solvent with aqueous media. Finally, although CNSL promotes the formation of the conductive emeraldine salt form of PAni, increasing CNSL concentrations appear to plasticize the PAni polymer, leading to reduced electrical conductivity. However, this reduction is not detrimental, and PAni nanofibers remain semiconductive even under high CNSL concentrations.
