The crystalinity of the system was calculated using data extracted from x-ray diffraction (XRD). The film was characterized by impedance spectroscopy HIOKI 3531-01 LCR Hi-Tester to measure its ionic conductivity over a wide range of frequency between 50Hz-5MHz and at temperatures between 298 K and 378 K. The result exhibit the advantages of ionic liquid as a charge carrier and also revealed that addition of 5% of BMIMNO3 shows the highest conductivity of (2.26�0.96) x 10-4 Scm-1.Conductivity-temperature relationship indicate that the system seems to obey the Vogel-Tamman-Fulcher (VTF) behaviour. � 2019 Trans Tech Publications Ltd, Switzerland.en-USChitosanIonic conductivityPolymer electrolyteStarchVTF behaviourBiomoleculesChitosanIonic conductivityIonic liquidsStarchBiopolymer electrolyteImpedance spectroscopyPolymer electrolyteSolution-casting techniqueStarch blendsVTF behaviourPolyelectrolytesArticle177182290 SSP
