摘要: Polymer electrolyte membranes, comprising of poly(methyl methacrylate) (PMMA), lithium tetraborate (Li2B4O7) as salt and dibutyl phthalate (DBP) plasticizer were prepared using a solution casting method. The incorporation DBP enhanced the ionic conductivity polymer electrolyte. containing 70 wt.% methacrylate)–lithium 30 wt.% presents highest 1.58 × 10−7 S/cm. temperature dependence study showed that these electrolytes obey Vogel–Tamman–Fulcher (VTF) type behaviour. Thermogravimetric analysis (TGA) was employed to analyse thermal stability electrolytes. Fourier transform infrared (FTIR) studies confirmed complexation between methacrylate), DBP.
