synthesis and characterization of fictionalized ionic liquids for enhancing the properties of some polymeric composites
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 1H-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). Functionalized ionic liquid 1-carboxymethyl-3- methylimidazolium bromide ionic liquid [CmMIM]Br IL had been synthesized with high product yield >90% and reported through quaternization reaction. The prepared IL was verified through Fourier Transform Infrared (FT-IR) spectroscopy. The ionic liquid [CmMIM]Br was used to modify the surface of magnesium hydroxide (MH).
