Abstracts: Polymer blend electrolytes composed of poly(acrylonitrile) (PAN) and poly(methyl methacrylate) (PMMA) as host polymers and lithium perchlorate as a salt were prepared by solution casting technique. The electrolytes were prepared for different ratios of host polymers with standard weight ratio of the ionic salt (LiClO 4). Among the different concentrations, the polymer electrolyte film containing PAN/PMMA (75:25 wt.%) was found to be a suitable candidate for the battery applications on the basis of ionic conductivity and thermal stability. Complexation, structural reorganizations and ionic conductivity as a function of temperature were studied using X-ray diffraction analysis, Fourier transform infrared, and ac impedance analysis, respectively. Thermal stability of the electrolyte film having maximum ionic conductivity was also studied using thermogravimetric analysis. © 2012 Springer-Verlag.

Plasticized polymer electrolytes comprising of ethylene carbonate as the plasticizing agent in poly (vinyl chloride) [PVC]–poly (butyl methacrylate) [PBMA] blended polymer electrolytes were prepared by solution casting technique. Complex formation, structural elucidation, conductivity, dielectric parameters (Ɛ′, Ɛ″, M′, and M″), thermal stability, and surface morphology are brought out from FTIR, XRD, ac impedance analysis, dielectric studies, thermogravimetry/differential thermal analysis, and scanning electron microscopic studies, respectively. Polymer electrolytes are found to exhibit higher ionic conductivity at higher concentration of plasticizer at the cost of their mechanical stability. Conductivity of 1.879 × 10−4 S cm−1 is exhibited by the polymer electrolyte consisting of 69% of plasticizer with appreciable thermal stability up to 523 K. Temperature and frequency dependence of conductivity is found to follow Vogel Tammann Fulcher relation and Jonscher power law, respectively. Real and imaginary parts of dielectric constants are found to decrease with increase in frequency which could be due to the electrode polarization effect. © 2017, Springer-Verlag Berlin Heidelberg.

Influence of plasticizer on ionic conductivity of PVC-PBMA polymer electrolytes

Poly(vinyl chloride) (PVC)—poly(butyl methacrylate) (PBMA) blended polymer electrolytes with lithium perchlorate (LiClO4) as the complexing salts are prepared by solution casting technique. The addition of PBMA into PVC matrix is found to induce considerable changes in physical and electrical properties of the polymer electrolytes. Addition of PBMA into PVC matrix is found to increase the conductivity by two orders of magnitude (1.108 × 10−5 S cm−1) when compared with that of the pristine PVC polymer electrolyte (10−7 S cm−1). Structural, thermal, mechanical, morphological, and polymer–salt interactions are ascertained from X-ray diffraction (XRD), thermogravimetry/differential thermal analysis (TG/DTA), mechanical analysis, scanning electron microscope (SEM), and Fourier transform infrared spectroscopy (FTIR) respectively. A thermal stability upto 250 °C is asserted from the TG/DTA analysis. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44939. © 2017 Wiley Periodicals, Inc.
