“…However, from Figure (b‐e) in the present work, it has been accomplished that both Zn(OTf) 2 and SiO 2 completely dissociates in the blended polymer matrices since there are no traces of crystalline and semi‐crystalline peaks corresponding to those in all the nanocomposite complexes. It has been found that the peak at 2θ = 20.3° obtained for the gel polymer film S0 gets shifted from 20.3° in S0 to lower 2θ values (19.8, 18.2, and 19.3°) in gel composites accompanied with the gradual decrease in the intensity and increase in the broadening of the peaks appreciably for the films from S1 to S3, and thus the amorphous phase is maintained up to 3 wt % addition of SiO 2 to S0 .…”

Zinc ion conducting nanocomposite gel polymer electrolytes (NCGPEs) comprising of poly(vinyl chloride) (PVC)/poly(ethyl methacrylate) (PEMA) blend, zinc triflate [Zn(OTf)2] salt, 1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIMTFSI) ionic liquid (IL) and fumed silica (SiO2) viz. [PVC/PEMA–Zn(OTf)2–EMIMTFSI–SiO2] exhibited the highest ionic conductivity value of 6.71 × 10−4 Scm−1 at room temperature. The ion–filler–polymer interactions and probable conformational changes observed in the structure of the gel composites due to the entrapment of IL and dispersion of nano‐sized SiO2 were confirmed from X‐ray diffraction (XRD) and Attenuated total reflection‐Fourier transform infrared (ATR‐FTIR) spectroscopy. Scanning electron microscopic (SEM) images of NCGPEs demonstrated uniform surface with abundant interconnected micropores. The cationic transport number of NCGPE samples has been found to be appreciably enhanced up to a maximum of 0.69 thus demonstrating a considerable improvement in Zn2+ ion conductivity. The NCGPE film possesses an electrochemical stability window up to 5.07 V (vs. Zn/Zn2+) and ensures feasible zinc stripping/plating in the redox process. The addition of SiO2 into the gel polymer electrolyte system has effectively reduced the glass‐transition temperature (Tg) of the NCGPE films and also accomplished improved thermal stability up to approximately 180 °C which were ascertained from Differential scanning calorimetry (DSC) and Thermogravimetric (TG) results. © 2019 Wiley Periodicals, Inc.

“…Peak due to the vibrational modes of PF 6-anion has been observed at 950 cm -1 . Asymmetric stretching observed on peak keeps on changing with change in the nanofiller concentration in the composite phase [18].This asymmetry in the anion stretching vibrational mode is an outcome of the degeneracy arising out of more than one contribution possibly due to the presence of free anion and ion pairs. 3.3.1 Polymer Ion Interaction Nano-filler effect substantial spectral change in the profile of FTIR spectrum of PEO host polymer by addition of nano-filler concentration in the wavenumber.…”

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.

“…Many techniques have been introduced to modify the structure of polymer electrolytes in order to improve their electrical, mechanical and electrochemical properties 7 . These approaches include: synthesizing new polymers 8 ; cross linking two polymers 9 ; blending of two polymers 10,11 ; adding plasticizers to polymer electrolytes 12 ; adding inorganic inert fillers to make composite polymer electrolytes 13,14 . Among these approaches, polymer blending is a useful technique for designing materials with a wide variety of properties by changing the composition of blend ratio.…”

Research on Polymeric materials have special interest in the recent years due to its high stability and hazardous free nature that are useful for the development of sensors, photovoltaic cells, high energy electrochemical devices, fuel cell etc. Solid blend polymer films have been prepared with the polymers polyvinylpyrrolidone (PVP) & polyacrylonitrile (PAN) by solution casting technique. The prepared films were investigated by different techniques. The XRD results confirms that the variation in the amorphous nature of the blend polymer with different blend-ratio. AC impedance spectroscopy has been used to examine the ionic conductivity and dielectric behavior of all the prepared blend polymer films was investigated in the frequency range 20 Hz to 4 MHz. The maximum conductivity has been found to be 4.45 × 10− 8 S cm− 1 at room temperature. The conductivity has been increased to 1.68 × 10−5 S cm−1 as the temperature is increased to 373 K. The activation energy of all the concentration of blend polymer was calculated using the Arrhenius plot and it is found to be 0.91 eV to 1.41 eV.
