Synthesis and characterization of functionalized ionic liquids for enhancing polymeric composites Synthesis and characterization of functionalized ionic liquids for enhancing the properties of some polymeric composites

Abstract

Abstract A series of 1-alkyl-3-methylimidazolium bromide [RMIM]Br ionic liquids had been synthesized and reported through quaternization reaction. High product yields were obtained (>90%). The synthesized ILs were verified through FT-IR and 1 H-NMR spectroscopy. The addition of ionic liquids to polymers has been reported to increase the polymer electrolytes conductivity. PMMA/[RMIM]Br polymer electrolyte films were prepared using solvent casting method. The physico-mechanical and dielectric properties were determined for prepared films with varied [RMIM]Br ionic liquids concentration from 0 - 7 wt%. The morphology of the polyelectrolyte films has been characterized by scan electron microscope (SEM).
