“…In particular, low amount of Ag + and Cu 2+ ( 0.5 M) produced PANI with very high resistance (> 200 M.ohm) and hence poor conductance value (see figure 2a and figure 2b). Such observation is not align with the findings of Diantoro et al [19] or Rahman et al [14] who demonstrated a higher electrical conductivity of the PANI upon doping with Ag + or Cu 2+ , as compared to the undoped counterpart. The detrimental effect observed in this study might be ascribed to partial blocking of conductive path by the metal dopant in the PANI matrix [16].…”

Conducting polymers possess inherent electrical conductivity, attracting significant attention in engineering applications, including dye-sensitized solar cells, gas sensors, and energy storage electrodes. Of various conducting polymers, Polyaniline has gained much attention due to its low cost of monomer, ease of bulk synthesis, high flexibility, and good environmental stability. Nevertheless, the conductivity of polyaniline is rather low when it is prepared under an un-doped state. Despite that, there is no clear information regarding how the valency of a metal dopant and its concentration can affect the electrical characteristics and other physicochemical properties of doped polyaniline. This study aims to fill this research gap by elucidating the changes in the electrical characteristics of polyaniline through metal doping. Polyaniline was synthesized through chemical oxidative polymerization in an HCl medium, followed by a post-doping to produce metal-codoped polyaniline. Three dopant materials, namely AgNO3, Cu(NO3)2, and Fe(NO3)3, were used in this synthesis, representing mono-, di-, and tri-valent metal ions, respectively. Results showed that bare PANI (which was doped with HCl only) exhibited a higher electrical conductance value of 8.44 x 10-7 S, while 1 M of Ag-codoped polyaniline, 1 M of Cu-codoped polyaniline, and 1 M of Fe-codoped polyaniline exhibited electrical conductance values of 1.73 x 10-7 S, 4.27 x 10-8 S, and 2.33 x 10-6 S, respectively. Apparently, the trivalent metal dopant was able to improve the conductivity of polyaniline; however, a detrimental effect resulted when the concentration of Fe3+ was increased to 1.5 M (overdose), resulting in a drop in electrical conductance to 4.66 x 10-8 S. In terms of morphological property, Ag-doped polyaniline exhibited a mixture of plate-like and globule-like structures, while both Cu-doped polyaniline and Fe-doped polyaniline predominantly displayed tiny globule-like structures, likely attributed to the stronger acidity of the Cu(NO3)2 and Fe(NO3)3 solutions. Meanwhile, the presence of several common bands of polyaniline such as N-H, C=N, C-H aromatic, quinoid and benzoid units are detected in the produced samples. The project outcomes are expected to guide tailored development of metal-doped polyaniline for specific electrical applications.

“…Although the crystallinity of general polymer can be improved by any specific treatment including heat and dopant, the crystalinity of flavonoid films lay below 10%. A similar dopant, heat treatment as well as ultrasonic irradiation effects also show similar result [22]. The crystallinity of JML and PIW-Ag/Ni films as a function of Ag concentration is depicted in Fig.3.…”

“…This conductivity is mostly driven by the presence of Ag ions as well as conjugated ion mobility. Although the electrical conductivity of the silver doped-flavonoids-Ag/Ni films is still one order of magnitude which is less than PANI-Ag/Ni films [22]. This results opens a wide range of research and its potential application.…”

Synthesis and characterization of highly purified nanosilica from pyrophyllite ores AIP Conference Proceedings 1719, 030020 (2016) A number of research have been reported related to broad synthesis method and mechanical properties. So far there is no specific report of electrical conductivity associated to PIW and JIL natural polymers. In order to obtain electrical conductivity and its crystallinity of the extracted polymer films, it was induced on them a various fraction of silver nano particles. The film has been prepared by means of spin coating method on nickel substrate. It was revealed that FTIR spectra confirm the existing of rutine flavonoid. The crystallinity of the samples increase from 0.66%, to 4.11% associated to the respective various of silver fractions of 0.1 M to 0.5 M. SEM images show that there are some grains of silver in the film. The nature of electric conductivity increases a long with the addition of silver. The electrical conductivity increase significantly from 3.22 S/cm, to 542.85 S/cm. On the other hand, PIW films also shows similar trends that increase of Ag induce the increase its crystallinity as well as its electrical conductivity at semiconducting level. This result opens a prospective research and application of the green renewable polymer as optoelectronic materials.

“…The speed of spin coating film 1500, 2500, and 300 rpm correspondingly displayed more excellent crystallinity at the lowest spin coating speed observed in the MZnONR1 sample. Addition of Mn2O3-AC-CB mass is due to the material composition, which is dominated by amorphous material [23,24]. [25,26], and wavenumber 860 cm -1 indicates the manganese carbonate phase has been completely transformed to manganese oxide [27].…”

One of Indonesia's most significant issues with technological growth is the lack of electrical energy storage devices. Active materials have low electrical conductivity, accessibility, and ion diffusion. Therefore, it is urgently required to study the combination of higher electrical conductivity ZnO and high surface area of AC-Mn2O3. However, ZnO nanorods (ZnONR) can be modified from ZnO nanoparticles (ZnONP). The structure modification may increase energy density due to having a higher surface area than ZnONP. Three different electrodes with AC-Mn2O3 addition various spin coated of 1000 rpm (MZnONR1), 2500 rpm (MZnONR2), and 3000 rpm (MZnONR3). The electrodes were then packaged in a sandwich flat symmetric supercapacitor. The characterization was carried out using X-RD, SEM-EDX cross-section, FTIR, and Cyclic Voltammetric. It is obtained that the highest specific capacitance showed by symmetric supercapacitor MZnONR1 with low speed of spin coating. We also found that the greater the deposited ZnNR content, the lowest thickness until 43.76 μm, the crystallinity until 62% and the highest porosity until 79%. This shows that the MZnONR1 sample exhibits the best electrochemical performance, which is supported by its morphological properties. It is shown that the higher the Zn content, the stability performance AC-Mn2O3 supercapacitor higher. ZnONR1 sandwich flat symmetric supercapacitor have a specific capacitance 0.0086 Fg-1 with an 0.00433 Whg-1 energy density. Furthermore, it was found that the addition of the AC-Mn2O3 increased 2800x compared to the ZnONR1, which reached 28.04 Fg-1 and an 14.09 Whg-1 of capacitance specific and energy density, respectively.
