Abstract:Castor oil-based polyurethane as a renewable resource polymer has been synthesized for application as a host in polymer electrolyte for electrochemical devices. The polyurethane was added with LiI and NaI in different wt% to form a film of polymer electrolytes. The films were characterized by using attenuated total reflectance-Fourier transform infrared spectroscopy, dynamic mechanical analysis, electrochemical impedance spectroscopy, linear sweep voltammetry and transference number measurement. The highest conductivity of 1.42 × 10 upon addition of 30 wt% NaI at room temperature. The temperature dependence conductivity plot indicated that both systems obeyed Arrhenius law. The activation energy for the PU-LiI and PU-NaI systems were 0.13 and 0.22 eV. Glass transition temperature of the synthesized polyurethane decreased from −15.8 °C to ~ −26 to −28 °C upon salts addition. These characterizations exhibited the castor oil-based polyurethane polymer electrolytes have potential to be used as alternative membrane for electrochemical devices.

Solid state polymer electrolytes have been prepared by with poly (ethylene oxide) (PEO), KBrO 3 salt and plasticizer (Dimethyle Formamide [DMF]) by using solution -casting technique. These polymer electrolytes have been prepared in the weight ratios (90:10), (80:20) and (70:30). The complexations of salt and polymer have been examined by using X-ray diffraction (XRD) and Differential Scanning Calorimetry (DSC). Carbon monoxide gas sensors have been fabricated by using (PEO+KBrO 3 +Plasticizer) polymer electrolytes and premeditated its sensitivities at various temperatures. The sensitivity of the gas sensor has been observed at various concentrations of carbon monoxide gas.

“…If the cations of KClO 4 get coordinated with the ether oxygen of PEO, the spectral changes are expected to be in the COC stretching and deformation ranges. The decrease in the width of 1117.7 cm -1 band, which is assigned to COC symmetrical and asymmetrical stretching [8]- [12], suggests the coordination / complexation of the salt with the polymer PEO.…”

Abstract-Growth of solid polymer electrolytes is driven by their tremendous technological applications. Therefore, solid-state polymer electrolyte have been prepared by solutioncasting method by using poly (ethylene oxide) (PEO), KClO 4 salt and Nano filler Al 2 O 3 . The complexation of poly (ethylene oxide) (PEO), KClO4and Al2O3 have been studied by using X-ray diffraction (XRD), IR and differential scanning calorimetry (DSC). Solid state electrochemical carbon monoxide gas sensors have been fabricated by using polymer electrolytes (PEO+ KClO4) and (PEO+ KClO 4 +Nano filler Al 2 O 3 ) and studied their sensitivities at different temperatures, and at different carbon monoxide gas concentrations. From these studies it is concluded that nano filler added polymer electrolytes sensor have more sensitivity when compared to the polymer electrolytes without nano filler.Index Terms-Polymer, poly (ethylene oxide), x-ray diffraction, gas sensor. I. INTRODUCTIONOver the last few decades, a considerable amount of research work has been reported on solid polymer electrolytes due to the technological advantages, such as long self-life, extreme miniaturization, wide temperature range of operation and they can be prepared easily with low cost. These solids exhibit appreciable high ionic conductivities at their operating temperatures [1]- [5]. Polymer electrolytes can be shaped in the form of thin film, there by reducing the internal resistance leading to gas sensing material application. A few of reports are materialized on proton conducting polymer electrolytes and their application to gas sensors. No attempts were witnessed for the preparation of sensors using ionic conductors. Keeping these aspects in view, the authors are used (PEO+ KClO 4 ) and (PEO+ KClO 4 +Nano filler Al 2 O 3 ) based polymer electrolytes which were fabricated by using solution casting technique. Complexation of the PEO and KClO 4 was confirmed by using X-ray diffraction (XRD), IR and differential scanning calorimetry (DSC). (PEO+ KClO 4 ) and (PEO+ KClO 4 +Nano filler Al 2 O 3 ) based polymer electrolyte carbon monoxide gas sensors were fabricated and studied their characteristics at different temperatures and also at different concentrations of carbon monoxide gas.
