Plasticized polymer complex films of polyethylene oxide with ammonium perchlorate (NH 4 ClO ) are synthesized by using solution cast technique. Propylene carbonate (PC) used as dopant to enhance conductivity electrolyte. The prepared characterized in detail X-ray diffraction, infrared spectral analysis, transient ionic current, and electrochemical impedance studies. electrolyte shows high (∼10 −4 S/cm) which appear novel for devices.
Abstract NH4ClO4 has a very high ionic conductivity ∼ 10−5 Scm −1 in which probable charge carrying mobile species is H+ ion apart from the anion ClO4−. The can be derived either –CH2‐CH2‐ of polymer PEO chain or NH4+ complexing salt. In order to identify and investigate its dynamics, wide‐line nuclear magnetic resonance (NMR) study been carried as function temperature. two types species, stated above, have found show different temperature dependence respective NMR‐linewidths. It established...
Abstract In solid–solid composite formation by dispersal of insulating filler in an ionic matrix results conductivity enhancement which has been discussed details this paper. Present system deals ammonium oxalate ((NH 4 ) 2 C O ·1H O) dispersed with (Al 3 ). Electrical, structural, and thermal studies viz. measurement, ion transport, transference number, infrared spectroscopy, differential scanning calorimetry are presented detail.
