“…This finding indicates that additional structural conversion has occurred, and the larger crystalline phase creates stronger ionic diffusivity, allowing enhanced ionic conduction. Increased crystalline nature may due to structural reorganizations due to presence of NC 40 . Moreover, based on XRD spectra degree of crystallinity was calculated shown in inset Figure 6.…”

Polyacrylonitrile (PAN) polymer blends were more in demand due to their wide range of applications. We overcome the restricted low thermal stability and poor strength for deployable blend. In the present study, we prepared PAN and nitrocellulose (NC) polymer blends by solution casting method to overcome the low loss, low dielectric properties as alternative blend for cladding purpose in communication domain. C≡N bond exclusively demonstrated the impact on blending was confirmed by Fourier‐transform infrared spectrophotometer (FTIR) and Raman microscopy measurement. Semicrystalline nature of polymer blends as a function of NC loading was determined by X‐ray diffraction (XRD). Optical polarizing microscopy (OPM) and scanning electron microscopy (SEM) analysis illustrated an appearance of micro flocculated spherulites. Blending ratio of PAN/NC demonstrated the decreased direct band gap identified by Ultraviolet spectroscopy (UV). PAN/NC proved excellent alternative as low dielectric constant and low loss as cladding medium. Blending of NC with PAN exhibited an increased hydrophilicity was confirmed by surface goniometer. Increased thermal stability of polymer blends was mapped by thermogravimetric analysis (TGA). Blend melting temperature and glass transition temperature was increased from 322°C to 334°C and 88°C to 102°C confirmed by Differential scanning calorimetry (DSC) analysis. Thermal conductivity was increased from ~0.13 to ~0.34 W/m. k for PAN/NC determined by Lee's disc probe method. Mechanical properties of blends were measured using universal testing machine (UTM). Tensile strength and Young's modulus was increased up to ~23%, and ~ 56%, whereas elongation break was decreased up to ~71% for PAN/NC blends compared to host PAN system. PAN/NC may suit promising candidate as cladding blend for communication engineering due to low loss and low dielectric constant.

“…Also, using the supporting solvents increased the conductivity of IL‐soaked Nafion membranes dramatically. It seems that the supporting solvent acts as a plasticizer and facilitates the free rotation of the molecular backbone causing an increase in backbone segment mobility . Components which increase the number density or the size of ionic clusters or the free volume available to polymer chain segments are expected to increase the conductivity of the Nafion membrane .…”

Electrolyte-soaked Nafion is commonly used as an ionic polymer in soft actuators. Here, a multitechnique investigation was applied to correlate the electrochemical behavior of Nafion membranes with their microstructures and nanostructures as a function of electrolyte type. The influence of electrolytes of Li salts with different counteranions on the Nafion membranes was investigated in terms of hydration level, structure (using X-ray diffraction and small angle X-ray scattering), stress-strain characteristics, and electrochemical behavior (by cyclic voltammetery and electrochemical impedance spectroscopy). The effects of using ionic liquid (IL), as the electrolyte, addition of different supporting solvent and the addition of Li 1 ions to water-free IL-soaked membranes on the structural and electrochemical properties of Nafion were examined. The nano-and microstructure of the Nafion changed considerably as a function of the identity of the electrolyte solution. The electrochemical behavior of the IL-soaked samples was compared with that of the water-soaked Li 1 -exchanged Nafion. It was seen that the ionic conductivity of the Nafion membranes was reduced significantly when water was replaced by pure IL. Using the supporting solvents increased the conductivity of IL-soaked Nafion membranes dramatically. The presence of a small amount of Li 1 ions together with the IL ions caused a significant decrease in charge transfer resistance and increases in double layer capacitance and in ionic conductivity over that of the water-free sample and also over watersoaked Li 1 -exchanged Nafion. These findings can be useful to improve the knowledge on Nafion's microstructure and also to improve the electromechanical behavior of Nafion-based ionic polymer-metal composites actuators.

“…Typically, several factors contribute to the ionic conductivity of the electrolyte such as ionic mobility, charge carrier concentrations and ionic charges in which the conductivity will be upsurge as the mobility of ions increases [44,45]. From Figure 9, the ionic conductivity increased as the amount of alumina decreased or x values increased which give the highest conductivity value of 1.8 x 10 -4 S.cm -2 when x = 0.9.…”

Composite solid electrolytes in the system (1-x)MgCO3 – xAl2O3 with x = 0.1 - 0.9 were synthesized by a sol-gel method and analyzed by X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, scanning electron microscopy, energy dispersive X-ray, Fourier transform infrared spectroscopy and alternating current impedance spectroscopy for the determination of the phases and crystallinity, thermal stability, surface morphology, elemental composition, chemical bonding and conductivity, respectively. The composites show that, the crystallinity of the composites decreases as the amount of Al2O3 increase which could lead to higher conductivity. The thermal decomposition studies also indicate that the melting and/or decomposition of the composites occur at lower temperature than the pure MgCO3 which normally take place at 350 oC. The composite with the ratio of x = 0.9 give the highest conductivity value in order of 10-4 S.cm-1 as compared to other ratio due to effective transfer of charge carriers in addition to the formation of MgO-Mg2+ species at the interface.
