Films of L-chitosan/PMMA blends and its complexes were prepared using a solution-casting technique. The ionic conductivity of the system was measured over a wide range of frequency between 50 Hz-1 MHz. Impedance plot for the samples demonstrates two well-defined regions. The disappearance of the high frequency semicircular region led to a conclusion that the current carriers are ions. Sample with 30 wt% of LiCF3SO3 showed the highest conductivity of 7.59 � 3.64 � 10-4 Scm-1 at room temperature. This is consistent with the results obtained from infrared spectroscopy. � 2014 Copyright � Taylor & Francis Group, LLC.en-USconductivityFTIRL-chitosanPMMApolymer electrolytesChitinChitosanElectric conductivityElectrolytesFourier transform infrared spectroscopyInfrared spectroscopyPolymersConduction propertiesCurrent carriersFTIRHigh frequency HFLithium triflatePMMAPolymer electrolyteSolution-casting techniquePolyelectrolytesArticle66726031MCLCD
