“…At higher frequencies, the ε r and ε i values are very low due to the strong periodic reversal of the electric field, which causes a reduction in a polarisation along the field direction [68]. No relaxation peaks are observed in figure 11, demonstrating that the rise in conductivity is mainly a result of the growth in the number density of mobile ions [69]. These findings imply that the electrode system is a non-Debye type [70].…”

This article presented new sequences of fish gelatin (FG) as a polymer host for solid polymer electrolytes (SPEs) impregnated with ammonium nitrate (NH4NO3) and the impact of different amounts of salt on the properties of the formed electrolyte were investigated. X-ray diffraction (XRD) analysis revealed that the electrolyte containing 25 wt.% NH4NO3 salt to be the most amorphous in nature. Fourier transform infrared (FTIR) spectroscopy analysis showed that the peak of amide III shifted to a lower wavenumber as salt increased to 25 wt.%, indicating the occurrence of interaction between the salt and polymer. The effect of variation amount of salt on the film morphology was studied using FESEM. The ionic conductivity of the undoped pure FG film at room temperature recorded a maximum value of (1.52±0.30)×10-5 S cm-1 at 25 wt.% NH4NO3 and the activation energy dropped to 0.454 eV. All electrolytes showed a linear conductivity-temperature plot at elevated temperatures, indicating that they all follow the Arrhenius rule. All of the electrolytes used in this study are non-Debye type, according to dielectric analysis. The findings provided in this article could help to improve the usage of FG as an alternate source of SPE in electrochemical power sources as a replacement for hazardous electrolytes.

“…e metal complexes of the ligand were investigated in relation to Co(II), Ni(II), and Zn(II). e copolymer-metal complexes were prepared in presence of ethanol as the solvent [18], whereby the synthesis of Co(II) complex of poly(DEAMSt0.49-co-BMA) was followed. For this purpose, 0.390 g (0.0008 mol) poly(DEAMSt0.49-co-BMA) used as the ligand was dissolved in 40 mL ethanol and was stirred at 65°C for 2 h, and the pH of the solution was calibrated by adding dilute 0.1 M NaOH solution in water.…”

In this paper, the copolymer of 4-diethanolaminomethyl styrene (DEAMSt) with benzyl methacrylate (BMA) was synthesized and characterized using various spectral techniques such as FT-IR, 1 H-NMR, elemental analysis, SEM, XRD, TGA, DTA, and DSC. e copolymer-metal complexes were prepared with Co(II), Ni(II), and Zn(II) metal ions, and poly(DEAMSt-co-BMA) was used as ligand. e copolymer-metal complexes were characterized using elemental analysis. FT-IR, SEM, XRD, magnetic measurements, and the thermal behaviors of the copolymer-metal complexes were studied using TGA, DTA, and DSC. e compositions of DEAMSt and BMA in the copolymer by 1 H-NMR spectra were determined as 0.49 and 0.51, respectively. Both poly(DEAMSt-co-BMA) and poly(DEAMSt-co-BMA)-Zn complexes were heated up to various temperatures. As the temperature increased, the intensities of O-H stretching bands at 3125-3429 cm −1 resulting from hydrogen bond decreased and shifted to high frequency. Gel permeation chromatography was used to determine the average molecular weights and polydispersity index of the poly(DEAMSt0.49-co-BMA) ligand. Both the molecular formula and C, H, and N % were estimated using elemental analysis, and the amounts of metal by mole (%) in the complexes were estimated by SEM-EDX measurements. e XRD patterns of ligand and metal complexes showed that they were of an amorphous nature. e synthesized metal complexes were annealed at 100°C for 1 h in order to obtain crystalline metal complexes. After annealing at 100°C, the metal complexes showed the crystalline structure. e SEM and XRD analysis of the metal complexes confirmed that metal ions contributed to the structure of the ligand. According to the magnetic measurements, it was suggested that geometrical structure for all complexes was tetrahedral geometry and the ratio of ligand to metal was found to be 2 : 1. e dielectric measurements of the ligand and its metal complexes were investigated depend on frequency.of ligands with transition metal ions [8][9][10]. Polymer metal complexes are used in many applications, such as alkali and alkaline earth metal ion separation [11], organic synthesis and nuclear chemistry [12], thermal stability, electrical conductivity, separation, photofunctions, catalytic activity, and biomedicine, gels, and ointments for medical use [13,14]. In addition, polymer-metal complexes are used as models for bioinorganic systems, as well as mechanochemical systems [11,15,16].In the present study, the poly(DEAMSt-co-BMA) was synthesized using free-radical polymerization, and this copolymer system was used as ligand. e copolymer-metal complexes were prepared with Co(II), Ni(II), and Zn(II) metal ions. e resulting copolymer and its metal complexes

 12 , G1  and H1  for the infinite diluted state were determined. The solubility parameters (2) of the copolymer were also found at the same temperature range. The solubility parameters (2) of P(DEAMSt%38-co-St) were found to decrease with the temperature increased. All thermodynamic results are based on the expected values for the polymer-nonsolvent systems of the probes used. The probes used were found to be not solvents for the copolymer under the glass transition temperature.
