“…3e. 46 PAN is also used for electrospinning, and the resulting membrane can be used as a supporting matrix to construct SCEs. 47 Due to the porous structure of the PAN matrix membrane, the ionic conductivity is enhanced to 7.1 × 10 −4 S cm −1 in the 3% nano-silica-PEO-PAN system.…”

“…The obtained solution is stirred at an elevated temperature of 60 °C-70 °C until a homogeneous slurry state was obtained. The slurry obtained is cast onto Teflon-coated glass plates and kept in the vacuum oven for drying at room temperature for 24 h and at 65 °C for 10 h to evaporate any residual solvents [30]. The resulting film was visually examined for its dryness and freestanding nature.…”

Plasticized Poly (vinylidene chloride- co- acrylonitrile) [P(VdC-co-AN)] polymer electrolytes comprising of Lithium Perchloride (LiClO4) as complexing salt and plasticizers such as Propylene carbonate (PC) and β‐butyrolactone (βbl) is prepared by solution casting technique. Polymer electrolytes were prepared in the ratio [(x)PVdC-co-PAN+(100-x-z) Plasticizer+(z) LiClO4] and were subjected to various characterizations. X-ray Diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) were carried out to study the structural and functional groups present in the material. Impedance spectroscopy to find the ionic conductivity of the material. The maximum ionic conductivity at room temperature was exhibited by the samples containing 68% PC (9.237 x 10-4 S cm-1) and 66% of βbl (2.284 X 10-4 Scm-1). Samples exhibiting higher ionic conductivity (68% PC and 66% of βbl) are subjected to Linear sweep voltammetry and transference number measurements. The electrochemical stability is 4.5 v for the both films, whereas transference number is 0.955 and 0.94, respectively. Thermogravimetry / Differential Thermal analysis (TG/DTA) shows the prepared films doesn’t not undergo any weight loss till 220°C (thermally stable). The surface morphology of the polymer membrane was explored through Atomic force microscopy (AFM).

“…25,26 To date, no reports are available explicitly for all solutioncast nanohybrid all solid state polymer membrane electrolyte (scHPME) using Na + -based nanofiller and PAN polymer matrix. 27,28 Hence, in the present work, we incorporated NMTO nanofillers into the PAN for the first time by a simple solution casting using a doctor blade technique. The prepared membrane was then activated in 1 M of sodium hexafluorophosphate (NaPF 6 ) in EC/DMC (1:1 v/v) electrolyte and then dried for use as an all solid state nanohybrid polymer membrane electrolyte to enhance its ionic conductivity and dielectric behavior.…”

Synergistically coupled inorganic−organic nanohybrids have emerged as a newer class of electrolytes inheriting high ionic conductivity and better thermal and mechanical stability. Herein, we reported the ionic conductivity and dielectric relaxation studies of all solid state PAN-Na 2 Mg 2 TeO 6 -NaPF 6 -based nanohybrid membrane electrolyte (scHPME) prepared by a simple solution-casting technique. The addition of different concentrations of Na 2 Mg 2 TeO 6 (NMTO) nanofiller (10, 20, and 30 wt %) into the host polyacrylonitrile (PAN) matrix improved their physiochemical and electrochemical behaviors. The influence of filler on the host polymer was studied in terms of crystallinity; thermal analysis and bond confirmation were done by using X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy, respectively. The ionic conductivity and dielectric relaxation measurements were conducted for the prepared all solid state PAN-Na 2 Mg 2 TeO 6 -NaPF 6 nanohybrid membrane electrolytes (scHPMEs). Among the investigated samples, 20 wt % NMTO embedded PAN matrix exhibited the highest ionic conductivity of 4.54 × 10 −4 S cm −1 at 25 °C. The present work provides an insight of filler engineering to tune the performance of all solid state nanohybrid polymer membrane electrolytes.
