“…Figure (a) shows the spectrum of PAN, where the peak at 2244 cm −1 was due to C≡N stretching vibrations. The peak at 1453 cm −1 confirmed the presence of CH 2 bending . Figure (b) illustrates the spectrum of P(VP‐ co ‐Vac), in which the peak at 1734 cm −1 was due to the CO stretching of poly(vinyl acetate) (PVAc) and the peak at 1660 cm −1 confirmed the presence of poly(vinyl pyrrolidone) (PVP).…”

“…From the XRD pattern of the PAN polymer, we observed that the characteristic peak at 17° indicated the semicrystalline nature and corresponded to the orthorhombic PAN (110) reflection. It also showed a broad peak at a 2θ of 28°, which described the amorphous region . We also observed that there were several diffractions in the XRD spectrum of NaI; these indicated the highly crystalline nature of the salt .…”

New gel polymer electrolytes (GPEs) were prepared via the blending of a polyacrylonitrile polymer and a poly(1‐vinyl pyrrolidone‐co‐vinyl acetate) copolymer. The sodium iodide (NaI) salt concentration was varied for each GPE sample. From ionic conductivity (σ) studies, we observed that the sample with a 40 wt % NaI salt content (N40) showed the highest σ of 3.54 × 10−3 ± 0.05 S/cm at room temperature, and all of the GPE samples obeyed Arrhenius behavior. The dielectric properties of the GPE samples were also analyzed to study the electrical polarization of the materials. The developed GPE samples were also characterized with X‐ray diffraction and Fourier transform infrared spectroscopy. We also then used the developed GPE samples for the fabrication of dye‐sensitized solar cells by sandwiching them between a photoanode and Pt counter electrode for photovoltaic studies. The highest photovoltaic performance was achieved by N40, with an efficiency of 3.04%. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47810.

A solid polymer blend electrolyte is prepared using poly(vinyl acetate) (PVAc) and poly(methyl methacrylate) (PMMA) polymers with different molecular weight percentage (wt%) of ammonium thiocyanate (NH 4 SCN) by solution casting technique with tetrahydrofuran (THF) as a solvent. The structural, morphological, vibrational, thermal and electrical properties of the prepared polymer blend electrolytes have been studied. The incorporation of NH 4 SCN into the polymeric matrix causes decrease in the degree of crystallinity of the samples. The complex formation between the polymer and salt has been confirmed by FTIR technique. The increase in T g with increase in salt concentration has been investigated. The maximum conductivity of 3.684 × 10 −3 S cm −1 has been observed for the composition of 70PVAc/30PMMA/30 wt% of NH 4 SCN at 303 K. This value of ionic conductivity is five orders of magnitude greater than that of 70PVAc/30PMMA polymer membrane. Dielectric and transport studies have been done. The highest conducting polymer electrolyte is used to fabricate proton battery with the configuration Zn/ZnSO 4 · 7H 2 O (anode) ||polymer electrolyte||PbO 2 /V 2 O 5 (cathode). The open circuit voltage of the fabricated battery is 1.83 V, and its performance has been studied.

Free standing transparent PNC (Polymer nanocomposite) films based on PEO/PAN + NaPF 6 with different concentration (wt./wt.) filler of nano sized (TiO 2 ) is synthesized by using standard solution cast technique. HRXRD (High resolution X-ray diffraction) and FESEM (Field emission scanning electron microscopy) have been performed to see the structural and microstructural behavior of the PNC films. The microscopic interaction among polymer, salt and nano-ceramic filler has been analyzed by FTIR (Fourier transformed infra-red) spectroscopy. The reduction of ion pair formation in polymeric separator is clearly observed on addition of nano-filler in the polymer salt complex film. Electrical (ionic/electronic) conductivity has been estimated (~ 10 -4 S/cm) optimized PNC films concentration of nanofiller (15 Wt.%). The estimated value of electrical conductivity is well corroborated by FTIR study. Thermal analysis has been done with thermo gravimetry analysis to find out thermal stability of PNC films. Transport properties associated due to majority mobile carriers ions and only negligible participation from electrons was observed through transport number analysis. The band gap (i.e. direct as well as indirect) decreases on the addition of nano-filler observed from the optical analysis. The estimated result of the prepared PNC films are at par with desired value for the device application.
